HUBBLE SPACE TELESCOPE DAILY REPORT #1195 PERIOD COVERED: 0000Z Daily Status Report as of 216/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed Two Sets of FOS/BL 5448 (Spacially Resolved Maps of Optically thick Accretion Disks: Cycle 4 High) The Faint Object spectrograph (Blue Side) was used to make ultraviolet spectrographic observations of the 13 th magnitude nova-like optically thick accretion disk of star UX-UMA to map out its structure. The observations were executed as planned, and no anomalies were reported. 1.2 Completed WF/PC-2 5369 (HST Medium-Deep Survey: Cycle 4 Medium High Gal. Lat) The WF/PC-2 made a series of observations of high latitude objects as part of a medium deep sky survey. The observations were taken in parallel with other prime science observations. An internal flat calibrations was also taken. The observations were executed as scheduled, and no anomalies were noted. 1.3 Completed FOS/RD 5529 (Cycle 4 FOS Discriminator Test) The Faint Object Spectrograph (Red Side) was used to run discriminator tests to determine if the discriminator settings need adjustment from the Cycle 3 Values. Dark, Internal Flat, and Wave calibrations observations were taken. The Observations were executed as scheduled, and no anomalies were noted. 1.4 Completed WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs) The WF/PC-2 was used to make snapshot observations of the nearby active galactic nuclei of NGC-4383, and NGC-1275 to study the interactions between the central engine, the stars, and the interstellar matter in the AGN. The observations were executed as scheduled, and no anomalies were noted. 1.5 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance Scale: Cycle 4 High) The WF/PC-2 was used to make images of galaxy NGC-7331 to be used in measuring the periods of Cepheid variable stars within the galaxies. The observations were executed as scheduled, and no problems were reported. 1.6 Completed Two Sets of WF/PC-2 5446 (The Nuclei of Nearby S0 and Spiral Galaxies: A PC Snapshot Imaging) The WF/PC-2 was used to make observations of the core region of galaxy NGC-7741 to provide statistics on the nuclear cups, stellar condensations, and inner stellar disks and dust lanes. The observations were executed as scheduled, and no anomalies were noted. 1.7 Completed Two Sets of GHRS/1 5595 (GHRS ECH-A Wavelength Monitor: Cycle 4) The High Resolution Spectrograph was used to make wavelength spectral lamp calibration observations to measure the instrumental characteristics of the Echelle-A spectrograph. The observations were executed as scheduled, and no anomalies were noted. 1.8 Completed WF/PC-2 5629 (WF/PC-2 Cycle 4 Photometric Calibration Monitor 1C: 4-Chip STD in F170W) The WF/PC-2 was used to make photometric calibration observations of the ultraviolet standard star GRW+70D582. The observations were executed as scheduled, and no anomalies were noted. 1.9 Completed WF/PC-2 5569 (WF/PC-2 Cycle 4 Calibration: Internal Flats) The WF/PC-2 was used to make flat field calibration images with the VIS lamp, and the internal source. Most of this observation was missing. Only a small part of the first data group was present. The problem was probably caused by the Science Data Formatter (CU/SDF) locking out. The problem is under investigation. The SDF was reset @ 216:18:00 z. 1.10 Completed FOC/96 5477 (Spectral Index Mapping and Secular Changes in the Jet of M-87: Cycle 4 High) The Faint Object Camera (f/96) was used to make observations of the nucleus, jet, and counter-jet in galaxy M-87. The observations were completed as planned, and no problems were reported. 1.11 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 High, High Galactic Latitude) The WF/PC-2 was used in parallel with the prime science observations to make high galactic latitude observations as part of a medium-deep sky survey. The observations were completed as planned, and no problems were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 5 Successful : 5 Scheduled Reacquisitions : 8 Successful : 8 2.2 FHST Updates: Scheduled :16 Successful :16 2.3 Significant HSTARs: HSTAR 4859: WF/PCII proposal 5570 part of observation lost due to an unexpected STR # 3 track change @ 214:23:45z. HSTAR 4860: OTA Thermal program crashed @ 215/20:40z. PRS doesn't support directive to initialize OTA Thermal program using the maneuver verification file. HSTAR 4861: FOS microprocessor bogged down @ 215:06:23z. FOS speed check counts indicated error in one major frame. Also occurred @ 215:10:08z. HSTAR 4862: CU/SDF lock-out @ 215:11:25z. Executive 402 message received @ 11:24z (AOS) caused by CU/SDF lockout. DCF reports only 128 packets of WF/PC observation 121 and only one packet from all subsequent WF/PC observations were received. See OR # 10167 & 10169 for recovery procedures. 2.4 Operations Notes: ********************** ********************** 3.0 ANOMALY STATUS: 3.1 Significant New Anomalies: None 3.2 Significant Unresolved Anomalies: None 4.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /Dave L. -END-
