Summary:
Observatory and instruments continue to perform nominally and according
to plan. COS NUV High-Voltage ramp-up is underway. The STIS mechanism functional has
checked out nominally. The first FGS2 observations have taken place as the initial part of the
AMA adjustment process.

Nominal. SKrol.
The load is centered around 73A and the system SOC is slowly continuing to
increase and reached 510Ah in the last orbit. The battery temperatures
remain low ranging between -4 and -1.0 deg C with excursions to just below
0 deg C when the redundant heater cycles on (once every 24 hour period).
EPS is closely monitoring the system as HST enters a beta peak that will
result in extended orbit day durations up to 69 minutes on DOY 158.
Nominal. JAbel
Monitoring and addressing equipment shelf temperature limits.

One SSR science dump and one engineering dump which include
quick-turnaround data scheduled in the next 24 hours.

• Status
o Operate/FUV Operate
o Vacuum gauge ~4.5e-6 torr
o Initial NUV turn-on and first 3 HV ramps completed
o OR 18465-0 successfully completed to clear COS event flag
2 to allow NUV commanding between parts 1 and 2
• Forward Plan
o OR to be submitted to clear COS event flag 2 between parts
2 and 3 for the NUV HV ramp
o To be submitted in coordination with STScI before
~152/16:29 UTC NUV Fold Test scheduled for 154/17:50
UTC
Science
• Nothing to add.
FGS/OTA



Engineering (ABradley, L Abramowicz-Reed)
• All hardware nominal, there are no new HSTARs.
• There were 9 GSACQs (Guide star pairs) spanning the previous 24
hours, all were successful.
• FGS 2 was used in Astrometry TRANS Mode 7 times, in preparation
for the AMA move on June 2. TRANS are in Clear and Pupil filters
and at 3 widely different position of the FOV.
o FGS2 working very well.
• Morgan and Wenz would like to present the charts tomorrow and
discuss the upcoming AMA move after the SMOV morning meeting.
Up-coming 24 hours:
• 5 GSACQs (Guide star pairs) and 2 sets of TRANS Mode scans with
FGS 2 are planned over the next 24 hours.
• There is also 1 FGS 2 ITS test in support of the AMA move.
Science
• Nothing to add.
• The new FGS has successfully acquired stars in a crowded field, as
part of the initial FGS2R AMA adjustment activity (proposal 11458).
• Linda will have further results, including more information on field
dependencies, later today.

• Status; Operate/SBC LV
o Nominal.
o WFC Optimization Campaign (OC) analysis is ongoing.
Expect further results later today.
o All temperatures and voltages nominal
• Forward Plan
o Update to ASIC FSW values needed based on analysis of
initial Oscilloscope data
 Plan for update to be presented at SMOV morning
meeting ~Tuesday
o Oscilloscope mode optimization iteration 2 scheduled to start
at 154/00:15 UT.
o Second End BEA check scheduled 156/06:32 UTC

 Status Operate/MAMAs 1&2 LVOn (SAA cycling)
 Mech functional appears all nominal
 MEB 1 Temperature (OMBT1) continues to flag high intermittently (~30.7
degC)
• HSTAR 11855 written to document limit violation.
o MEB1 temp up another count, 4 degrees to safing limit.
o Appears to be running 5 degrees warmer than previously,
and higher than predicted.
o All voltages and currents are nominal.

• The STIS mechanism
•
functional successfully executed this
morning
o including movements of the STIS CCD shutter, the
operation of which had not been verified during the FT
due to a commanding error.
Over the next few days, a substantial portion of STIS CCD
SMOV proposals will execute.
o Tonight the pre-anneal internal observations will be
taken
o Wednesday
 post-anneal observations
 CCD functional test
 checkout of apertures and lamps

CTI checks (including data for the B-amp that
showed anomalous behavior during the FT)
first external observations taken to verify the
STIS-to-FGS alignment.
