Observatory Status

The on-going SI calibrations are proceeding per plan and the analyses are revealing
no major concerns, though there are a few minor ones. With the exception of two
COS ERO visits to be repeated because of guidestar problems, all the ERO
observations have now been completed.
With a couple of minor exceptions, the remainder of WFC3 and STIS SMOV is
expected to complete by the end of next week.
However, a programmatic decision to emphasize high-priority, time-critical
science in SMS 243-250 means that most of the rest of COS SMOV and all of
NICMOS SMOV is deferred to mid-Sep.
The NICMOS instrument was brought up to SAAOper state shortly after the
meeting.
 Though the detectors are not yet in “Full” operate
 HST now has six science instruments (including FGS) in operate mode.
All subsystems are nominal
SI Status
o
o
WFC3
 Engineering
• The D2 Lamp Test (11428)
o At least one visit exhibited a delay in lamp turn-on
 ~ 21 min.
 Similar, shorter delays had been experienced on the
ground
o At least one visit was observed by Randy Kimble to turn on
without apparent delay.
o Scott Swain to investigate

Science (SDeustua)
• Synphot table updates have been generated on the basis of SMOV
data
o Estimate delivery to CDBS group next week
• Excess “afterglow” seen in CSM test (11421) and first reported last
week
o Under investigation
• Cross-SI Light Leak Test (11515)
o Continuing analysis

Engineering
•
New HVNom values loaded into the DCE last week
o Ops Rqst 18684-1

-
To load HVMax values into the DCE, need to cycle the HV
o Scheduled to be done out of sms236
Also need to perform a DCE memory dump
o For any evidence of past HV transients
Science DSahnow
• On-going analyses (all nominal, so far)
o FUV focus (and refocus planning)
o Target Acqs
o NUV sensitivities

NICMOS/NCS
 NICMOS instrument scheduled to be brought up to SAAOper today
• Note: Accomplished post-meeting at approximately 1615 UT.
o Mounting Cup temperature = 77.2 K
o HST now has 6 operating instruments (incl. FGS).
o
ERO
ACS SMOV is complete.
Science. CProffitt
• Only the MAMA Image Analysis (11395) remains to be executed
o Scheduled this week and next
• On-going analyses
o MAMA sensitivities - nominal
o NUV darks- nominal
o Echelle Mode throughputs
 E140H ~ 20% below expectations
• Reason unknown
• For details, see the attached SMOV_STIS_18aug2009.ppt

COS EROs 11503 and 11508
• Both experience guidestar failures
• Will be repeated early on SMS243
• That will complete the ERO data takes.

Calendar/SMS builds
 SMS236 is being built now
• Finals mode processing
 SMS243
• “Hunting & gathering” (of visits) will begin this week.
Replans
 SMS236 contains COS refocus
 SMS243 contains

COS ERO repeats (see above ERO entry)
COS FUV focus verification visits
Note: A programmatic decision to emphasize high-priority science in SMS 243250 has been made. This means that most of the rest of COS SMOV and all of
NICMOS SMOV will deferred to mid-Sep. (The small amounts of WFC3 and
STIS SMOV that remain are planned to complete without delay.)
