SMOV STATUS & PLANNING MEETING - 19 MAR. 97 NOTE: THE NEXT MEETING IS FRIDAY, MARCH 21, 8:30 AM. STATUS REPORTS 1. Observatory Status - All subsystems nominal MOSES reports that, per STScI request, the Secondary Mirror was adjusted in response to the latest monitored trends in desorption and the SMOV alignment/focus plans for STIS and NICMOS. The move amounted to -2.4 microns and was performed yesterday at ~ 5:30 pm. Battery 1 reconditioning has been performed and indi- cates a total of 84 amp-hrs of charge. This compares favorably to the 78 amp-hrs measured in 95 and 80 in 1994. 2. WFPC2 Status - Proceeding nominally with Cycle 6 science and remaining SMOV monitors. 3. NICMOS Status - Engineering status - The Detector temperature is ~60.4 degK and the VCS temperature is now ~99.9 degK Detector warming rates and VCS cooling rates were not available at this meeting. The Intermediate Alignment/Focus activity (7135) is proceeding nominally. The Camera 3 data, relevant to the determination of the latest Camera 3 focus position and to implied dewar expansion, will be dumped starting at 3:15 pm EST today. The Project has requested that the focus postion analysis from this activity, in parti- cular that for Camera 3, be expedited so that results can be presented by late Thursday afternoon. The NIMCOS team and Chris Burrows/STScI will do the analysis. Code 440 (Gerry Repass) will organize the Thursday afternoon meeting, the results of which will be used to decide if it is safe to allow filter wheel rotation for Friday's NICMOS IR check preceeding and following COSTAR FOC arm deployments. The first relevant NICMOS activity starts Friday morning at 4:18 am EST (080/0918z). The NICMOS/FGS Alignment activity (7039), scheduled to start tomorrow morning at 9:36 am EST, can be accomplished without the need for filter wheel rotations. (Upon receipt of the 7135 data, OPUS is to FTP it to "thunder" as well as to Burrows' workstation.) An HSTAR had been written against a PAM motor temp monitor which seems to have toggled out of limits for 1 sample at 16 degC. Not considered a problem. - Science Status - Nothing new to report 4. STIS Status - Engineering Status - Nominal. HSTAR 5982 was written against a CCD Motor Temp which toggled out of limits at 14.3 degC. This is not considered to be real. - Science Status - The CCD UV Monitor that occurred last Saturday night has been analyzed. The results are within 1% of the previous UV monitor thereby indi- cating no loss of UV sensitivity between the two obser- bations. The data from the Spectroscopic Mode Image Quality activity (7077) have been analyzed and the results are very good (1.7 - 1.8 pixels FWHM). However, the rate of hot pixel creation is 4 or 5 times higher than ground-based expectations (~100 pixels per 10 days at counts greater than 1 electron/px/sec), which is also causing a slight increase in overall dark current. The PDB update and table updates needed for STIS CCD Acq Test (7067) in SMS083 have been submitted. 5. FGS status - No new activity. 6. FOC/COSTAR status- no new activity. The FOC COSTAR mirror arms are scheduled for deployment on Friday. The NICMOS request to delay the deployment until the lifting of the embargo on NICMOS filter wheel motion (for the 7054 pre- and post-arm deployment IR check) has been disap- proved by both the SMOV TTRB and the Project. Instead, the COSTAR arm deployment will proceed as planned and a decision to enable filter wheel motion for 7054 will be made beforehand (See NICMOS status above.) PLANNING REPORTS 1. Status of Upcoming SMSs - SMS076- Currently executing. - SMS079 - Signed off. - SMS083 - Initial Mode products are available for review on AP7. The new executable for the MEGG fix is expected on Wednesday. This SMS implements the SSR for engineering data record. This SMS also has been modified to include the Target of Opportunity identified lst week. - The STIS SIAF PDB updates for this SMS will be submitted in two segments, one for the first part of the SMS and one for later. The first update has been submitted. - SMS090 - Initial Mode products are available for review on AP7. Initial calendar build has begun. SARs are out. A "10.2" commanding update is also needed for this SMS. The NICMOS ERO 7111 (OMC1) has been removed from this calendar, revised to use camera 2 instead of camera 3, and is slated for SMS097. - SMS097 - Being built. - SMS104 - Will require a "10.2 commanding update for NICMOS SAA avoidance and for STIS CCD annealing process. This update is on schedule. The annealing proposal (7107) can go in this SMS. 2. Replans STIS - MAMA HV Turn-on (7105) is delayed (from 21 March) indefinitely. Affects on downstream MAMA scheduling will be assessed. NICMOS - None yet identified. OPERATIONS STATUS 1. OPUS - Nominal. Science data processing is proceeding with no new problems. A "quick fix" is expected to resolve OPUS problems in processing about 5-6 hours of engineering data from March 4 and March 12. a "re-use target offset" which OPUS will execute. 2. Archive - Nominal.
