PHOTO-HELIOGRAPHIC RESULTS
INTRODUCTION
The photographs from which these measures were made were taken at the Royal
Greenwich Observatory, the Royal Observatory, Cape of Good Hope, and the Kodaikanal
Observatory, Southern India.
The photographs of the Sun obtained at Greenwich were taken w i t h the 4-inch
Photoheliograph, of which the original object-glass had been replaced in 1910 by a
Grubb photographic objective.
The equivalent focal length of the photoheliograph
with its present enlarging system (supplied in 1926 by Ross, L t d . ) is 67^ feet, the
diameter of the Sun's image at the secondary focus being approximately 7^ inches.
On 1949 May 2 this photoheliograph was moved from Greenwich to Herstmonceux Castle,
Sussex. Subsequent photographs continue to be designated "Greenwich" photographs.
The photographs of the Sun obtained at the Cape Observatory were taken under
the superintendence of Her M a j e s t y ' s Astronomer at the Cape, Dr. R. H. Stoy, and
those from Kodaikanal under the superintendence of the Director, Dr. A. K. Das. At
the Cape Observatory the instrument employed was a 4-inch photoheliograph giving an
image of the Sun about 7^ inches in diameter; at Kodaikanal a Cooke photo-visual
o b j e c t i v e of 6 inches aperture was used, the image of the Sun which was obtained
being of about the same size.
Photographs of the Sun were available for measurement on 363 days in 1955,
those finally selected for measurement being supplied by the different observatories
as under:

For the two missing days, copies of original solar negatives were kindly supplied
by the Mount Wilson Observatory, California, and the Fraunhofer I n s t i t u t , Freiburg
im Breisgau, Western Germany. The names of the measurers of the photographs for the
year 1955 were as follows:
H. Barton
P. A. Wayman
N. Rhodes
P. S. Laurie
A. S. Milsom
Miss B. J. Denman
At the p r i m a r y f o c u s of the photoheliographs at Greenwich and the Cape two
spider-wires are fixed by which the zero of position-angles on the photographs can
be determined. These wires are inclined at an angle of 45° to the celestial equator.
In the K o d a i k a n a l instrume.nt there is one w i r e f i x e d p a r a l l e l to the e q u a t o r .

INTRODUCTION то GREENWICH PHOTO.HELIOGRAPHIC RESULTS, 1955.
The precise zero of position-angles for ^he photoheliographs has been determined
by three different methods.
(i) Zero Photographs. Plates were exposed twice, with an interval of about 100
seconds between the two exposures, the instrument being firmly clamped. Two images
of the Sun, overlapping each other by about a fifth part of the Sun's diameter, were
thus produced upon the plates. The exposures were so made that the line joining the
cusps passed approximately through the centre of the plates and the inclinations
of the two spider-wires to this line were measured. A small correction for the
inclination of the Sun's path has been applied. Two or three zero photographs were
usually taken each month at Greenwich, the Cape, and Kodaikanal.
(ii)
Transits. At Greenwich and the Cape, transits of the Sun were taken visually,
the times of contact of the first and second limbs of the Sun with the two wires
being noted by an eye-and-ear method. The ratio of the time taken by the Sun to
pass over the NE - SW wire to the time taken to pass over the SE - NW wire was used
in order to find the angle made by the Sun's path with the bisectors of the wires.
From this, again incorporating a correction to allow for the inclination of the
Sun's path, the orientation of the wires with respect to the N - S line could be
inferred. Transits were usually taken at Greenwich and the Cape on four or more
days during each month.
(iii)
Supplementary Zero Photographs. At Greenwich supplementary partial images
of the Sun were occasionally recorded on otherwise normal photographs, a second
exposure being made after clamping the instrument firmly for 130 seconds. The small
portion of the Sun's limb visible at the western edge of the plate could be used,
together with the main image which it does not intersect, to deduce the orientation
of the wires in a way similar to that used for the zero photographs. Six to ten
supplementary zero photographs were taken at Greenwich each month. The values for
the zero of position-angles deduced from them were given half weight in the adoption
of zero-corrections to be used in the reduction of photographs.
The following table gives the zero-corrections determined by the various
methods at Greenwich and the Cape during 1955, together with the adopted values.

In the case of the few Kodaikanal photographs individual values were adopted,
as indicated by the appropriate zero photographs.
The measures of the photographs were made with a large position-micrometer
that can be used for photographs of the Sun up to 12 inches in diameter.
In this
micrometer the photograph is held with its film-side uppermost on three pillars
fixed on a circular plate, which can be turned through a small angle about a pivot
in its circumference by means of a screw and antagonistic spring acting at the
opposite extremity of the diameter.
The pivot of this plate is mounted on the
circumference of another circular plate which can be turned by a similar screwaction about a pivot in its circumference.
This pivot, 90° distant from that of the
upper plate, is mounted on a third circular plate, with a position-circle graduated
in divisions of 30 minutes of arc, which may be rotated about its centre. By this
means small movements in two directions at right angles to each other can be readily
given and the photograph can be accurately centred with respect to the centre of
rotation of the position-circle.
When this has been done, a Ramsden eyepiece,
having at its anterior focus a glass diaphragm ruled with cross-lines into squares
with sides of one hundredth of an inch (for measurement of areas), is moved along a
slide adjusted so that the centre of the eyepiece moves diametrically across the
photograph, the diaphragm being nearly in contact with the photographic film, so
that parallax is negligible.
The distance of a spot or facula from the centre of
the disk is read from a scale and vernier to l/250th of an inch, corresponding to
0.001 of the Sun's radius for images 8 inches in diameter.
The posit ion-angle is
read from the large position-circle which rotates with the photographic plate. The
photograph is illuminated by diffused light reflected from white paper placed at an
angle of 45° below the photograph.
All photographs were measured independently by two measurers.
In the case of large or complex groups of spots, the chief components were
measured individually; so also in the case of groups near to the east or west limbs
of the Sun where the effects of foreshortening are appreciable. In other cases the
position of the centre of a group was estimated by the measurer at the micrometer.
In this respect a difference has been made from the practice during years prior to
1916 when, in the Daily Results (§1.), components of groups were given separately,
and in the Ledgers (§3.) combination into groups was made.
When required, corrections have been applied to the measured distances and
position-angles to allow for differential refraction. The details of this correction

were given in the I n t r o d u c t i o n for 1909.
It is necessary to apply t h i s c o r r e c t i o n
to about twenty per cent of the photographs taken at Greenwich in the months October
to March.
§1.
P o s i t i o n s and A r e a s of S u n s p o t s
and F a c u l a e for
e a c h Day in the Y e a r 1955.
In t h i s section the measured p o s i t i o n s and areas of sunspots and faculae are
given for each day. The positions of sunspots are referred f i r s t l y to a system of
apparent polar co-ordinates on the Sun's d i s k and secondly to a system of heliographic co-ordinates.
The p o s i t i o n s of faculae are g i v e n only in apparent polar
co-ordinates.
The calculations of heliographic longitude and l a t i t u d e are made from formulae
given by W. de la Rue, B. Stewart and B. Loewy, P h i l . T r a n s . , 1869.
The system of
heliographic co-ordinates may be defined as follows.
The i n c l i n a t i o n of the Sun's
axis to the ecliptic is assumed to be 82°45', the longitude of the ascending node of
the S u n ' s e q u a t o r on the e c l i p t i c for 1955.0 to be 75°07'. 9, and the p e r i o d of
the Sun's sidereal rotation to be 25.38 days. The m e r i d i a n which passed through
the ascending node on 1854 January 1, Greenwich mean noon, is taken as the zero
meridian and longitudes increase from east to west. The mean synodic rotation-period
is 27.2753 d a y s ; s y n o d i c r o t a t i o n - p e r i o d s are counted from 1853 November 9, in
continuation of Carrington's series.
Let r be the measured distance of a spot from the centre of the Sun's apparent
disk and y the position-angle of the spot from the Sun's axis, R the measured radius
of the Sun on the photograph, S the tabular semi-diameter of the Sun in arc, and
p, p' the angular distances of a spot from the centre of the apparent d i s k , as
viewed from the Sun's centre and from the Earth respectively. p - the heliocentric
angle - is obtained from the following e q u a t i o n s :
p' = -| S and sin
(p + p' ) = I
If Bo and Ф are the heliographic latitudes and L0 and X the heliographic
longitudes of the Earth and the spot respectively,
sin ф = cos p sin Bo + sin p cos Bo cos y
sin (bo - X) = sin y sin p sec Ф
у is found from the position-angle measured eastwards from the north point of
the Sun's disk by subtracting P, the position-angle of the north end of the Sun's
axis also measured eastwards from the north point. The three quantities P, Bo and
Lo for the time of the exposure of each photograph are derived from the Ephemeris
for Physical Observations of the Sun, given on p. 340 of the Nautical Almanac for 1955.
§2.
General Catalogue of Groups of Sunspots for 1955.
This catalogue first contains particulars of every group of sunspots which
Lasted for two or more days during 1955. The group numbers are in continuation of
those given in 1954 and previous years; the Mount Wilson group numbers are also
given. The table includes an indication of those groups which may be considered to
be members of "recurrent series" of groups, as contained in Ledger I below (§3.).
Spot groups seen on one day only are given in a separate table, where they
receive a distinctive numeration.

"Revival" groups of apots have been tabulated in series in a table
the General Catalogue.
§3.
following
Ledgers of the Areas and H e l i o g r a p h i e P o s i t i o n s of Groups of Sunspots for 1955.
The groups of w h i c h d e t a i l s are given in these ledgers have been a b s t r a c t e d
from a general ledger of all spot groups seen throughout the year. Apart from
the groups, there are printed in a similar manner d e t a i l s of i n d i v i d u a l components
of the principal groups. This has been done in all cases where it appeared probable
that an i n d i v i d u a l component l a s t e d to the second or t h i r d r o t a t i o n a f t e r its
f i r s t appearance.
Ledger I. - R e c u r r e n t Groups. The groups contained in this ledger were selected
upon the f o l l o w i n g plan, reference b e i n g made to the General Catalogue:- If any
spot when f i r s t seen was 60° or more to the east of the central m e r i d i a n , the
catalogue and, if necessary, the Daily Results also (§1.), were searched some f i f t e e n
to sixteen days e a r l i e r to ascertain whether a spot group of s i m i l a r h e l i o g r a p h i c
longitude and latitude was then near the west limb o-f the Sun. Similarly, if any
spot group when last seen was 60° or more to the west of the central m e r i d i a n , a
search was made f i f t e e n to sixteen days later. When there appeared to be a case of
probable continuity between groups in consecutive rotations of the Sun, the character
of the groups, t h e i r areas and t h e i r longitude and l a t i t u d e have been c a r e f u l l y
compared before a c c e p t i n g them as a recurrent group.
Ledger II. - Non-Recurrent Groups. This ledger contains those groups lasting
for six days or longer w h i c h are not members of recurrent series.
§4.
Total Areas, Mean Areas and Mean H e l i o g r a p h i c L a t i t u d e s of Sunspots and Faculae
in the Year 1955.
This section contains total areas of sunspots and faculae for each day in the
year, together w i t h mean areas and mean h e l i o g r a p h i c l a t i t u d e s of sunspots and
faculas for each Rotation of the Sun during 1955. Similar annual mean values are
also given.

filaments seen on the Sun's disk near sunspots and (2) observations of solar flares
in Hen light. The observations were made p r i n c i p a l l y w i t h a spectrohelioscope lent
by the Mount Wilson Observatory in the autumn of 1929 and set up at Greenwich in
the south a t t i c of the Main B u i l d i n g and, since 1950 February, at Herstmonceux
in a spectrohelioscope room forming the ground floor of the dome housing the photoheliograph. The instrument is of a type described by G. E. Hale in the A s t r o p h y s i c a l
J o u r n a l , 70, 265, 1929. The spectrum is formed by a Rowland g r a t i n g ruled w i t h
14,438 lines to the inch. The f i r s t order spectrum around Ясс is normally used, the
scale being 1 mm. - 4.35 A. The w i d t h of the second s l i t is usually 0.1 mm. The
diameter of the monochromatic image of the Sun's disk at the second s l i t is about
50 mm., of w h i c h a p o r t i o n 28 mm. x 6 mm. is rendered v i s i b l e by the r o t a t i o n
rectangular prisms.
The e y e p i e c e used g i v e s an o v e r a l l m a g n i f i c a t i o n of x40,
approximately. A second spectrohelioscope of similar design, presented in 1949 by
Mr. A. M. Newbegin, is also available when required so that simultaneous observations
can be made by two observers. The observations during 1955 were made by H. Barton,
P. S. Laurie and N. Rhodes.

ROYAL GREENWICH OBSERVATORY
General Catalogue
of Groups of Sunspots
For the year 1955
G R E E N W I C H PHOTO-HELIOGRAPHIC RESULTS, 1955
GENERAL CATALOGUE OP GROUPS OP SUNSPOTS POR THE YEAR 1955.
Groups of s u n s p o t s , l a s t i n g for two or more d a y s , are n u m b e r e d in the f i r s t column in
continuation of the group-numbers given in 1954 and the previous years. Groups seen only once are
not included in this catalogue but are given with a distinctive numeration in a following table
on p. С 45.
The second column gives the corresponding Mount W i l s o n group number, as i d e n t i f i e d from
the bi-monthly summaries of the Mount W i l s o n magnetic observations of sunspots p u b l i s h e d in
P u b l i c a t i o n s of the A s t r o n o m i c a l S o c i e t y of the P a c i f i c .
The third column gives the U.T. of the central meridian passage of each group as deduced from
its mean longitude (given in the e l e v e n t h column). For those groups which are in existence at the
time of the central meridian passage of their longitude, the time is given to OrOl, corresponding
to 0.13 of solar longitude.
In other cases, in which groups disappear before or appear after the
central meridian, the deduced time is given to 0.1.
The fourth column gives
which are not seen upon the

of observation.
the duration of each group in days. Intermittent groups, i . e . , groups
photographs of every day between their f i r s t and last appearances,
the numerator of which represents the number of days on which they
denominator being the number of days covering the extreme limits
The s i x t h and e i g h t h columns, headed "Longitude from central meridian", give, for the days on
which each group was f i r s t and l a s t seen r e s p e c t i v e l y , the h e l i o g r a p h i c l o n g i t u d e f r o m the
meridian passing through the centre of the Sun's disk at the time of observation, longitudes west
of the centre being reckoned as positive.
The mean areas for umbrae and whole spots entered in the n i n t h and t e n t h columns are corrected
for the e f f e c t of foreshortening and are expressed in millionths of the Sun's v i s i b l e hemisphere.
The e l e v e n t h and t w e l f t h columns give the mean heliographic position of the group in longitude
and latitude respectively.
The t h i r t e e n t h column gives reference to all groups contained in L e d g e r I and Ledger II; for
a group in Ledger I both its recurrent series number and its order in the series are also given.
W i t h r e f e r e n c e to the i d e n t i f i c a t i o n both of recurrent and revival groups, it should be
noted that longitudes are based on the ephemeris given in the H a u t i c a l A l m a n a c , assuming a solar
rotation period constant at all latitudes. After an interval of one rotation, recurring groups
w i l l , t h e r e f o r e , show in general - apart f r o m any proper motion they may have of their own apparent d r i f t s in longitude v a r y i n g in amount according to their respective latitudes. The
following table, derived from the f o r m u l a Ë, = 14°37 - 2?60 sin 2 Ф, gives the apparent d r i f t in
longitude appropriate to d i f f e r e n t l a t i t u d e s a f t e r an i n t e r v a l of 27 days, a d r i f t f o r w a r d s
corresponding to an increase in heliographic longitude.

REVIVAL GROUPS OF SUNSPOTS
Groups of spots occupying the same heliographic position in consecutive disk passages (partial
or complete) but with definite breaks in their history are termed 'Revivals'. Such groups have
been abstracted from the preceding catalogue and are grouped in series in the following table.
When a 'Recurrent' series i.e. Ledger I forms part of a 'Revival' series, a reference is given in
the last column of the table. Groups that are given in detail in Ledger II are also indicated.

GREENWICH PHOTO-HELIOGRAPHIC
RESULTS, 1955
LEDGERS OP GROUPS OF SUNSPOTS FOR THE YEAR 1955.
LEDGER ï. - RECURRENT GROUPS
LEDGER n. - NON-RECURRENT GROUPS
The time (U. T. ) at which, the photograph was taken is expressed in the first column by the
day of the year and decimal of a day reckoned from Greenwich mean midnight.
The place where the photograph was taken is also indicated in the first column. A photograph
taken at Greenwich is indicated by the letter G, and those taken at the Cape, Kodaikanal, Mount
Wilson and Freiburg, by the letters, C, K, Mt. W and F respectively.
The projected area of the umbrse and whole spots, given in the second and third columns, is
the area as it is measured on the photograph, uncorrected for the effect of foreshortening, and
expressed in millionths of the Sun's apparent disk.
The area corrected for foreshortening given in the fourth, and fifth columns is expressed in
millionths of the Sun's visible hemisphere.
The longitude given in the sixth column is based on the ephemeris given in the Nautical
Almanac, assuming a daily sidereal motion of 14.18, due to the Sun's rotation, constant at all
latitudes; this corresponds to Carrington's assumed rotation period of S5.38 days.
The proper motion given in the seventh column is derived from the difference of longitude
thus computed from the measured positions on any given day and the first day on which the group of
spots or single spot is visible, after the correction for the motion appropriate to the latitude
has been applied according to the formula, Ç = 14°37 - 2?60 sin2 Ф. A plus sign (increasing
longitude) indicates a motion forwards, a minus sign a motion backwards relative to the position
on the first day.
The remaining columns correspond to those with similar headings in the preceding section.
When a group is 80 or more from the Sun's central meridian, the measures for that day are
not included in taking the mean area or the mean longitude and latitude of the group. In such
cases of close proximity to the Sun's limb, the addition of brackets denotes that only part of
the group is visible.

MEAN AREAS OF SUNSPOTS AND FACULJE FOR EACH ROTATION OF THE SUN,
FROM 1964
DECEMBER 22
TO 1956
JANUARY 7
The mean, areas have been formed by taking the means of the areas for each day of observation
throughout each rotation of the Sun, the projected areas being the areas as measured on the
photographs and expressed in millionths of the Sun's apparent disk, and the areas corrected for
foreshortening being expressed in millionths of the Sun's visible hemisphere.
The rotations adopted in the following table (which is in continuation of those for the years
1873-1954 printed in the Greenwich Observations for 1884 and succeeding years) correspond to the
synodic rotation of the Sun, and the commencement of each is defined by the coincidence of the
assumed prime meridian with the central meridian, the assumed prime meridian being that meridian
which passed through the ascending node of the Sun's equator on the ecliptic at mean noon on
January 1, 1854, and the assumed period of the Sun's sidereal rotation being 25.38 days. The
numeration of the rotations is in continuation of Carrington's series (Observations of Solar Spots
made at R e d h i l l by R. C. Carrington, F.R.S.), No. 1 being the rotation commencing 1853 November 9.
The dates of commencement of the rotations are given in U.T.

MEAN HELIOGRAPHIC
LATITUDE
FROM 1954
OF SUNSPOTS FOR EACH ROTATION
DECEMBER 22 TO 1966 JANUARY
С 75
OF THE SUN,
7
The numbers given in the accompanying table have been formed as follows: The heliographic latitude of each spot for each day has been multiplied by its area (corrected
for f o r e s h o r t e n i n g ) , and the sum of the p r o d u c t s , for spots north of the equator, has been
divided by the sum of the corresponding areas to form the mean heliographic latitude of spotted
area north of the equator; s i m i l a r l y for spots south of the equator.
In forming the mean
heliographic latitude of entire spotted area, the algebraic sum of the products for spots north
and aouth of the equator has been divided by the sum of the areas; and for the mean distance
from the equator of all spots the numerical sum of the products,! without regard to the sign of
latitude, has been similarly divided.
The mean areas have been formed by dividing the sum of the daily areas (corrected for foreshortening) by the number of days of observation for each rotation of the Sun and are expressed in
millionths of the Sun's visible hemisphere.

GREENWICH PHOTO-HELIOGRAPHIC RESULTS, 1955
Blank page retained for pagination
OBSERVATIONS OF SOLAR FILAMENTS MADE
WITH THE SPECTROHELIOSCOPES
IN THE YEAR 1955
The following observations relate to dark filaments visible on the Sun's disk
in the light of Ha. in the immediate v i c i n i t y of sunspots*.
Measures of line-of-sight velocity are taken w i t h the "line-shifter", whose
scale from 0 - 1 0 divisions = 0.37 A. = 17 km./sec. at Ha.. The zero of the Ha. line
is determined from measures of the darkest part of the line in an undisturbed portion
of the Sun near the centre of the disk. The purpose of the observations being to
locate large line-of-sight velocities*, measured displacements are i n t e r p r e t e d
as being due to Doppler effects.
The probable error of a single measure of line-of-sight velocity, as determined
from a number of successive readings, is about 3 km./sec., including the probable
error of the zero determination. Three or four measures being generally made on
each filament, the probable errors of the tabulated values in the third column of
the following table do not usually exceed 2 km./sec., except, perhaps in the case of
the larger v e l o c i t i e s , which have accordingly been rounded off to the nearest
5 km./sec.
In the following table, the headings of which are self-explanatory,
are given of each dark filament as follows (1)
particulars
The measured line-of-sight velocity in km./sec., + indicating motion away from
the observer and - motion towards the observer.
Where two values are given it is to be understood, unless otherwise stated
in the footnotes, that different velocities were observed along the length of
the filament, and that the tabulated values are the extreme velocities measured,
which in nearly all cases correspond to the opposite ends of the marking. In
those cases in which one end of a f i l a m e n t , showing progressive v e l o c i t i e s
along its length, appeared to touch a sunspot, the l i n e - o f - s i g h t v e l o c i t y
observed at that extremity of the filament is printed in italics.
(2)
(a) The apparent length of the filament in minutes of arc, read by means of a
scale inserted in the field, or from a drawing. An asterisk denotes that the
marking was small and roughly c i r c u l a r in shape. The d i a m e t e r s of these
circular markings are of the order of 10".
* An analysis of the line-of-sight velocities of dark Ha. markings near sunspots, observed at
the Royal Observatory, Greenwich, 1930-33, is given in Monthly Notices, 94, 472, 1934.
A further
paper on the characteristic motions of such filaments associated with solar flares appears in
Monthly n o t i c e s , 102, -2, 1942.

GREENWICH PHOTO-HELIOGRAPHIC RESULTS, 1955.
(b) The apparent least distance in minutes of arc from the centre of the
nearest sunspot or group of spots. In those cases indicated by dots in the
appropriate column it was not possible to obtain a measure.
(c) The position of the filament relative to the group of associated sunspots
or to a single component of the group. In cases where a sunspot has been so
designated in the Ledgers in the preceding Results, the appropriate letter a
(the leader of the group) or ò (the follower) has been added. The abbreviations
n, s, f, p, c, stand respectively for north, south, following, preceding, central.
(3) Particulars of the associated group of sunspots, abstracted from the General
Catalogue, including the longitude Crorn the Sun's central meridian at the time
of observing the filament (deduced from the mean longitude of the sunspots).
Notes have been added of unusual features seen at the time of observation.
Filaments which were apparently descending into sunspots with progressive velocities
and which showed a definite curvature of shape are also noted.

OBSERVATIONS OF SOLAR FLARES MADE
WITH THE SPEGTROHELIOSCOPE
IN THE YEAR 1955
Observations in Яа-light of solar flares, otherwise bright chromospheric
eruptions, were be.gun at Greenwich when the spectrohelioscope was installed in 1929.
The observed t i m e s of f l a r e s and t h e i r p o s i t i o n s have s i n c e 1935 been regularly
communicated to Meudon for incorporation in the Q u a r t e r l y B u l l e t i n on Solar A c t i v i t y
published from Zurich under the auspices of the International Astronomical Union.
I n v e s t i g a t i o n s made at Greenwich into the r e l a t i o n s h i p s between solar f l a r e s and
(l) r a d i o fade-outs
(2) geomagnetic disturbances are published in M o n t h l y N o t i c e s
97, 594, 1937; 103, 244, 1943 and 104, 4, 1944.
The included t a b l e g i v e s d e t a i l s of f l a r e s observed at the Royal Greenwich
Observatory in the year 1955.
This table continues the l i s t of flares given in the
1953 volume and preceding volumes s i n c e 1944.
The f o l l o w i n g is an e x p l a n a t i o n of
the material contained in the v a r i o u s columns:
Column 1.
Keference-number of the
flare.
Columns 2, 3 and 4. Date and approximate times (U. T. ) of observation. Times in
heavier type denote that the beginning or the end of the flare was actually observed.
Columns 5, 6 and 7. Radial d i s t a n c e (in terms of the Sun's apparent r a d i u s ) ,
l a t i t u d e and longitude from the central m e r i d i a n of the flare when observed.
Column 8. The observer's estimate, when it occurs w i t h i n the times of observation, of the time of maximum of the flare.
In c e r t a i n cases t h i s t i m e of maximum
has been derived from a series of i n t e n s i t y or l i n e - w i d t h measurements.
Column 9. Approximate area of the f l a r e , corrected for f o r e s h o r t e n i n g and
expressed in millionths of the Sun's hemisphere. A g r a t i c u l e inserted in the f i e l d
of view has been used for the measurement of area.
Column 10. The magnitude, estimated by the observer,
scale 1-2-3, as used in the Q u a r t e r l y B u l l e t i n .
on an a r b i t r a r y ascending
Columns 11 and 12. The h i g h e s t measured value of the l i g h t - i n t e n s i t y (not
necessarily obtained at the t i m e of maximum given in Col. 8) e m i t t e d by the f l a r e
and the time (U.T.) of the observation.
The i n t e n s i t y is expressed as a percentage
of the local continuum and is corrected for scattered light in the instrument. W i t h
a visual wedge photometer a measure is usually taken of the r a t i o of b r i g n t n e s s of
the flare to the brightness of the undisturbed disk, at the central wavelength of Ha.
The following apparent central i n t e n s i t i e s (obtained experimentally and uncorrected
for instrumental scattering) are assumed at the various p a r t s of the d i s k in order
to o b t a i n the a p p a r e n t i n t e n s i t y of the f l a r e in terms of the local c o n t i n u u m :

The value for the centre of the Sun's disk indicates the presence of scattered light
of about 9 per cent; the intensities given in Column 12 incorporate the appropriate
correction according to the procedure given in M o n t h l y Notices, 96, 5, 1935.
No
correction is made for finite slit-width since such correction, for the centre of
the //cc-line, is not expected to exceed one or two per cent.
In some cases (indicated by italicized figures in Column 12) the measurement of
the intensity is made directly with the local continuum. A secondary "line-shifter"
(see Monthly Notices, 99, 463, 1939) is used to bring the continuum 15 A.U. from the
centre of the Яа-line into the lower half of the field to enable the comparison to
be made. A correction to allow for the absorption (15 per cent) of the thick lineshifter is made and the correction for scattered light can then be applied, as in
the other cases.
Columns 13 and 14. The reference number, in the General Catalogue, of the spot
group associated with the flare and the position of the flare relative to the group
or, in some cases, a principal component a or 6, as designated in the Ledgers.
Column 15. The reference number from the preceding table of line-of-sightvelocity measures of any dark filament observed in close association with the flare.
