HUBBLE SPACE TELESCOPE DAILY REPORT #1088 PERIOD COVERED: 0700 EST Daily Status Report as of 063/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: Internal Monitor 3: Darks) The WF/PC-2 was used to obtain several 30 minute long dark exposures to provide ongoing calibration of the CCD dark current and to monitor and characterize the evolution of hot pixels. The observations were received and examined in the OSS and looked as expected. 1.2 Completed FGS 5061 (Linking HIPPARCOS to the Extragalactic Reference Frame, Part 4 of 6) The Fine Guidance Sensors were used to make astrometric observations of star NEWEGOB-34 whose apparent position lies near an extragalactic object. The intent of these observations is to tie the reference frame to the extragalactic reference frame. Except for a few recenterings, all observations were reported to be nominal. 1.3 Completed FGS 5331 (Linking HIPPARCOS to the Extragalactic Reference Frame, FT1-11, Part 7) Fine Guidance Sensor #3 was used to make astrometric observations of stars, 1150+497IN and INCA221-72 and nearby extragalactic objects which are known to have a small angular separation. The baseline guide star acquisition got fine lock. There was one reported recentering event. 1.4 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 Medium, 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 main purpose of these observations is to study the evolution and structure of galaxies. Eight observations were received and displayed in the OSS. Many of the observations received recentering events, but otherwise looked okay. One observation still remains on the science tape recorder. 1.5 Completed WF/PC-2 5209 (Luminous Stars in Old Stellar Populations) The WF/PC-2 was used to make observations of globular cluster NGC-6681 to look at old luminous stars. Observations were made at both the visible and ultraviolet wavelengths. The observations were successfully completed in fine lock, and they were monitored by the OSS. No anomalies were noted. 1.6 Completed WF/PC-2 5436 (Age and Population of Super Metal Rich Globular Clusters) The WF/PC-2 was used to make observations of the super metal rich globular cluster TARAZAN-1 located in the central bulge of our galaxy. The hope is to determine the age of this cluster. All observations were completed in fine lock. The observations were monitored in the OSS, and the data quality was assessed. No anomalies were noted. 1.7 Completed WF/PC-2 5204 (The Disk Around Young Stellar Objects) The WF/PC-2 Camera was used to make observations of the variable proto star T-Tauri located in the Taurus molecular cloud to examine the disk known to be around this stellar object. It is hoped that this will determine the physical properties, albedo, particle size, and its spatial distribution of particles in the disk. The baseline acquisition occurred during LOS. The observations were made in fine lock, and the recentering counter had not been incremented. The observation complete as expected. 1.8 Completed FGS 5174 (Astrometric Companions Search: Cycle 4) FGS #3 was used to make astrometric observations of the possible binary dwarf star BD+68D946 to look for an astrometric unseen low mass companion. The OSS monitored the observations and assessed the data quality. No anomalies were noted. 1.9 Completed WF/PC-2 5091 (GTO High Latitude Parallel Program: Cycle 4) The WF/PC-2 was used in parallel with the prime science observations to make high galactic latitude observations greater than +/-30 degrees. These are randomly chosen fields to sample very low luminosity stars in the solar galactic neighborhood, galactic halo objects, and distant galaxies. The observations were executed as scheduled, and no anomalies were noted. 1.10 Completed WF/PC-2 5233 (Stellar Populations and Clusters in Elliptical Galaxies (WC08)) The WF/PC-2 was used to make deep observations of elliptical galaxy NGC-4881 which is located in the Coma Cluster of galaxies to study its stellar population. This is to help determine the distance to the Coma Cluster. The observations were complete as scheduled, and no anomalies wereoted. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 13 Successful : 13 Scheduled Reacquisitions : 9 Successful : 9 2.2 FHST Updates: Scheduled :7 Successful :7 2.3 Significant HSTARs: None 2.4 Operations Notes: SMOV activities were executed without incident, and all HST susbystems reported nominal performance. 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete FOC/96 5146 (Ultraviolet Observations of Globular Clusters) 3.2 Complete WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4) 3.3 Complete Three Sets of WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies) 3.4 Complete WF/PC-2 5350 (The Fossil Record of Star formation in the Leo I and Fornax Dwarf Galaxies) 3.5 Complete Two Sets of WF/PC-2 5392 (Mapping Io's Surface and Volcanic Activity: Cycle 4 Medium) 3.6 Complete FGS 5061 (Linking the HIPPARCOS to the Extragalactic Reference Frame.
