STATUS REPORTS



1.  Observatory Status



	MOSES status reports:

	- PCS reported another guide star failure at 068/0532, which

 	  again was a WFPC2 Cycle 6 science observation.  The

	  observation proceeded on one guide star in FGS3.



	- All other observatory subsystems are nominal.





2.  WFPC2 Status - Proceeding mnominally with Cycle 6 science and

	remaining SMOV monitors.

	

3.  NICMOS Status



	- Engineering status - John Bacinski/STScI reported the

	results of his investigation into thermal behavior from

	day 045 to day 068 (Sat. evening).  Prior to last week's

	inflection point, the Vapor Cooled Shield (VCS) had been

	cooling, per expectations, at about 2 degK/day. Since that

	time, the rate of temperature decrease has varied but seems

	to have settled in at around 6 degK/day.  The last data

	points may even be the first indications of a slow-down in

	this rate.  The absolute VCS temperature is now around

	118 - 120 degK, compared to last week's post-inflection

	expectations of ~ 130 degK.  The cold well temperature is

	currently between 57 and 59.5 degK, with a rate of increase

	that is apparently constant.



	- Science Status - The STScI and IDT are in agreement on the

	decision to proceed to coarse alignment and on the relevant

	parameters involved in its exection.  The Coarse Alignment

	activity (7041) is scheduled for tomorrow afternoon.  Prior to

	that time, NICMOS will be brought from BOOT to OPERATE after

	the most intense SAA orbits have completed.



	

4.  STIS Status



	- Engineering Status - Over the weekend there was a Cal Insert

	Mechanism (CIM) re-try, the soecond of SMOV (HSTAR 5973).



	The operational workaround to correct the STIS data record

	problem reported in the notes from the last two meetings was

 	successful each time it was needed this weekend for the 

	STIS 7075.



	- Science Status - The data from the 3 iterations of

	of Coarse Corrector Alignment (7075) look good.  The Coarse

	Corrector alignment activity is therefore complete and

	successful.  This, along with a PDB aperture file update

	and slit location table updates, will enable the Point Source

 	Acq Test (7067) starting in the SMS083.



	The "time-tag generic slew request" to correct the

	pre-alignment offset in the UV monitor (7063) target position

	was performed yesterday and the observation was successful.



5.  FGS status - no new activity.  Preparations for the FF3

	Optimization Activity (7026) are in place for the

	3 visits scheduled today and tomorrow.



6.  FOC/COSTAR status- no new activity

  



PLANNING REPORTS
