SMOV Status & Planning Meeting Minutes

Meeting Date: 04/14/97


		SMOV STATUS & PLANNING MEETING -  14 APR. 97



NOTE:  The next meeting is April 16, 8:30 AM.


STATUS REPORTS

1.  Observatory Status - All systems nominal.

	Following last week's Safemode, the Observatory resumed science/SMOV
	operations at noon Friday (101/1600z).  Over the weekend, there
	were several SRR limits violations while in the SAA, but there were
	no details available at this meeting.

	The PCS dropped to RGA hold at 102/1934z when FGS3 had problems 
	maintaining lock on a faint guide star.

	All else nominal.

2.  WFPC2 Status - Proceeding nominally with Cycle 6 science and
	remaining SMOV monitors.  
  

3.  NICMOS Status

	- Engineering Status - 

	The cold well (ice) temperature is 59.9 degK, and appears stable.

	The VCS Cold Mask temperature is 97.7 degK., and appears to
	have switched from last weeks small warming trend to a small cooling
	trend.

	In general the indications continue to indicate approach to
	thermal equilibrium.
  
	The NICMOS Dewar heaters suffered two more SAA-induced 
	thermal set point corruptions, one on Friday which was corrected
	per STOCC procedure, and one on Saturday which was corrected by the
	SMS-provided set-point refresh (See notes from 11 April).  


  	- Science Status - 

	ERO data reduction continues.  The preliminary data from the most
	recent ERO observation, 7111 OMC-1, "looks neat".

	Because of the safemode-induced delay in the Absolute Photometry
	Test (7049), the Team has been using other sources, including the
	alignment target, to determine photometric accuracy.  So far the
	analysis shows counts at about 70% of the level expected by the
	Team's handbook, which, however, did not include the effects of
	pupil plane blockage.  So far only Cameras 1 & 2, each in only a
	couple of filters, have been studied.  But these results, as well
	as data from the FOM test, provide even more confidence in the
	favorable indications of a very low thermal background.
	The corresponding changes to the on-line Exposure Time Calcu-
	lator, which had been based on more pessimistic expectations, have
	already been made.

	As was noted in Friday's report, the exposure times for 7034 FOM test
	were designed too short to provide good PSF information at
	various FOM positions.  In addition, it has become apparent the test
	was not designed properly to test for FOM position repeatability,
	which was to be a primary goal.  For these reasons, the NICMOS team
	is requesting a one-orbit repeat of a slightly modified test.  The 
	request will be processed through the SMOV Management Team.

 
4.  STIS Status

	- Engineering Status - Nominal.  Some more low-limit temperature
	violations on the optical bench have occurred, but these have been
	seen before and are understood.

	- Science Status - Nothing new to report.  The first visit of the
	STIS ERO 7124 has occurred overnight.

5.  FGS status - No new activities.

6.  FOC/COSTAR status- The FOC SMOV program is complete.  The SMOV TTRB has
	enabled the resumption of FOC science.  The FOC was recovered rou-
	tinely from last week's spacecraft safing.


PLANNING REPORTS

1.  Status of Upcoming SMSs


	- SMS104 - Currently executing.

	- SMS111 - Built but needs to be rerun to include latest FGS
		K-factors.  Final Mode products are expected Wednesday
		or Thursday of this week.


	- SMS118 - Needs to be rerun to include latest FGS K-factors.
		 - SARs were sent out over the weekend.
  		 - This SMS will, according to Rodger Doxsey's latest
		   MAMA activiation plan, will include 7105 MAMA HV Turn-on.
		 - The problems with the STIS doppler correction routines
		   need to be worked out before further MAMA
		   doppler-dependent activities can be scheduled.  Harry
		   Ferguson has provided a list of the affected proposals.

	- SMS125 - Being worked this week.


2.  Replans

	STIS

	- MAMA HV Turn-on (7105) is currently planned for SMS118.
	  Downstream MAMA scheduling is being assessed.  According to
	  the latest estimates, regular MAMA SMOV operations should start
	  in the SMS 139.

	NICMOS

	- No significant replans have yet been identified.


OPERATIONS STATUS

1.  OPUS - All associated data sets from NICMOS ERO 7111 had problems
	   in CALNIC-A.  Problems are being investigated; meanwhile all
	   data has been FTP's to the Team.
  

	"Re-use Target Offsets" are planned this week for
	a NICMOS activity and a STIS ERO.

2.  Archive - Nominal.
