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
