SMOV Status & Planning Meeting 03/03/97

SMOV Status & Planning Meeting Minutes

Meeting Date: 03/03/97


STATUS REPORTS

1.  Observatory Status

	MOSES status reports:

	-PCS - Nominal
	     - Gyro biases continue to be monitored.
	     - The first STIS acquisition was monitored closely
		in case of any acquisition problems.  There were
		none.
	     - RWA1 is being monitored during slews, especially
		now that we are out of the BEA period.

	- Other observatory subsystems all nominal

2.  WFPC2 Status 
	- Engineering status is nominal.  A DECON is scheduled
	  for tonight.

	- Science status - nominal.  UV throughput continues to
	  be monitored with no significant difference from
	  pre-SM2 measurements.

3.  NICMOS Status

	- Engineering status - NICMOS experienced another 
	  transition to SUSPEND state this morning at 12:32 UT.
	  The event appears to have the same signature as the
	  previous transition to SUSPEND, occurring again deep
	  in the SAA.  This time, however, it occurred on
	  Detector 3 instead of 1.  There will be a meeting later
	  this morning to firm up plans for any realtime manipula-
	  tions that need to preceed the scheduled Pre-Alignment
	  Check-out (7134) scheduled to occur tomorrow.  
	  
	  There is also a 5:30 pm (EST) meeting
	  today to discuss the NICMOS SAA Contours Test, scheduled
	  farther downstream in SMOV.

	- Science Status - nominal - Data analysis continues on 
	  previously executed internal activities.  A report on
	  part 2 of the Parallel Operations Test (7136) will be
	  out soon.

4.  STIS Status

	- Engineering Status - Nominal - The MAMA LVPSs remain
	  off indefinitely, pending further investigation by BASD.
	  The Ball ground testing has produced a few instances of HV
turn-on while simulating the in-orbit conditions for the
	  MCE reset anomalies.  Life testing of the Band2 flight spare
	  is being conducted in order to determine safe ramp
	  times as a potential operational implementation for MAMA
	  high-voltage operations.  The STIS bulkhead is running
	  several degrees cooler than anticipated because the MAMA
	  LVPSs are off.  Meetings tomorrow and, if necessary, through
	  the rest of the week, will determine if the SMOV schedule
	  is impacted in any way by these problems.

    	- Science Status - STIS reports that the first STIS 
	  external observation, a star field viewed by the CCD 
          for the purpose of STIS/FGS alignment (7065) is a success.
	  The target appears well centered in the FOV with a FWHM
	  of less than 2 pixels and only a slight hint of coma.
	  Data analysis is still in the early stages but the STIS
	  astronomers who have seen the image are quite pleased.

	- The STIS team also report a red leak in the MgII filter
	  and a pinhole in the 270 continuum filter.  In
	  addition the fiducial (0.2 X 0.2) aperture displays a small
	  amount of orbital motion (0.15 pixels), attributable to
	  STIS heater cycling.  These problems are all characterized
	  as minor.
 
5.  FGS status - no activity
	  The first FGS1R activity (7026, visit 1) is scheduled
	  for later this morning.

6.  FOC/COSTAR status - nominal - no activity
	  The FOC non-COSTAR baseline throughput measurements (7012)
	  are scheduled for this evening.


PLANNING REPORTS

1.  Status of Upcoming SMSs

    	- SMS062 - Currently executing.
		
   	- SMS065 - Signed off, rady for uplink.

   	- SMS069 - Finals are out for review.

  	- SMS072 - Built and initials out for review

	- SMS076 - Built and initials out for review

	- SMS079 - Initial build complete.  This SMS currently
		   contains the 1st part of the MAMA HV turn-on, 
		   per the nominal plan.

2.  Replans - none

OPERATIONS STATUS

1.  OPUS - A fraction of STIS data is not making it through
 	calibration, partly due to an IRAF kernal problem that
	will be corrected this week, and partly due to misconfigured
	flags and reference files in the pipeline.  All problems 
	have operational workarounds in place and permanent
	corrections planned.
 
2.  Archive - Nominal
