STATUS REPORTS

1.  Observatory Status

	MOSES status reports:

	-PCS - nominal - Proposal 7028 executed successfully,
		returning HST to fine-lock guiding (FGS 2&3)
`
	-EPS - nominal - SADE timing will continue to be monitored.

	-DMS - nominal - SSR is currently continuously recording
		engineering data (SMS053).

	-Thermal - nominal.

	-FSW - STIS 4.5 patch installation was carried out.
		(Hand-out provided by SI/MOSES.) STIS was
		returned to HOLD mode to await SMS reconfiguration.
		Post-installation EEPROM memory dump was verified by
 		BRZ updated to match on-orbit SI configuration.		

2.  WFPC2 Status - nominal - successfully transitioned from SAFE 
	to HOLD.  CCDs at +22C.  AFMs at -43C.
				
3.  NICMOS Status - During execution of proposal 7033, two status
	buffer messages were issued due to an improperly commanded
	NICMOS memory monitor word during the memory self test.  The
	second was due to a memory dump time-out because of improper
	SDF conditioning by the SMS commands for dumping.  (Details
	in hand-outs provided by both STScI and MOSES.)  The 
	NICMOS EEPROM and CS buffer memory were dumped successfully 
	in real-time.  Now nominal.

4.  STIS Status - During proposal 7058 (STIS Memory Load & Dump),
	the instrument suspended, reporting two status buffe messages.
	Both were related to the attempt to invoke an OPERATE-mode
	macro while in BOOT mode.  The SI was recovered by PSTOL
	commands. (Details in a MOSES-provided hand-out.)
	Now nominal, although the IDT reports that 28-volt noise
	problem has reappeared without any reconfiguration of FOC/PDU
	(See notes from 22 Feb meeting.)  Believed to be understood
	as some sort of amplification effect.

5.  FGS status - nominal - no change from last report

6.  FOC/COSTAR status - COSTAR DOB was successfully deployed, but not
	before a safing event caused by a mis-match between actual
	start position and the position expected by new NSSC1 FSW.
	(Details in STScI-provided handout.)

PLANNING REPORTS

1.  Status of Upcoming SMSs

	- SMS053 (1st SMOV Science SMS) - Uplinked and 
	  executing.
	
          The goal is to run all of the SMSs through SMS069 by
	  Sunday for input to commanding review in order to 
	  get a jump on TDRS requests in forecast period.
 			
	- SMS055 - Signed off. Ready for uplink.
 
   	- SMS058 - Has beem built and finals have been delivered
		for review.

	- SMS058H - (contingency SMS058 in case WFPC2
 			contamination is seen in SMS055)
		- Has beem built and finals have been delivered
		for review.

  	- SMS062 - built and under commanding review.  
		TDRSS requests being negotiated Monday morning during
		 Active Period. 

   	- SMS065 - built and under commanding review.  TDRSS requests
		being negotiated Monday morning.
 
   	- SMS069 - built and under commanding review.  TDRSS requests
		being negotiated Monday morning prior to forecast
		period.

  	- SMS072 - currently being built, expected tonight for initial
		SARs.


2.  Replans - none

OPERATIONAL ISSUES - As a result of the STIS and NICMOS operational problems
reported above, John Campbell requests a list
from the STScI of all SMOV proposals using special commanding and
requests a furhter review, on the part of the teams, of the upcoming 
activities in the current and next SMSs.
