Notes:
It was discovered by William Herschel
in 1780.
1822: 6.3 @ 262. Over 100
measurements.
The primary rotates at 180 kps.
The stars show similar proper motions.
95 Her (STF 2264)
Observed with C8
on 8/10/99; s7, t7
Magnification: 100x
Observations:
C8 at 83x. Wonderful! Some
observers report G and R, or Y and O.
Webb saw them as gY and rY. Smyth
called them "apple green and cherry red."
Webb wrote that there were "strange
discrepancies as to color." Described by
Smyth as 'apple green and cherry red.
Hartung said pY, dY.
Amateur reports include (yW, B), (pW,
gW), (Y, Y), (W, W or salmon), (pY, B?).

Notes:
AB 1878: 35.5 @ 34. 7 measurements. Star A is a spectroscopic binary with a 245.3
day period. It is also a strong infra-red source.
AC 1878: 40.7 @ 25. 4 measurements.
Burnham found a companion to B in 1877 (11.10m) at 7.0 @ 159. In 1915, the PA
was reported to be 325.
