HUBBLE SPACE TELESCOPE DAILY REPORT #2224 PERIOD COVERED: 0000Z (UTC) 10/06/98 - 0000Z (UTC) 10/07/98 Daily Status Report as of 280/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed Two Sets of STIS/CCD/MA2/WF/PC-2/NIC/1/2/3 8075 (HDF-South Observations) The WF/PC-2, The Space Telescope Imaging Spectrograph (MA2 and CCD) and the Near Infrared Camera (Cameras One, Two and Three) all were used to make deep observations of the Hubble Deep Fields- South (HDFS-22333). This program is designed to provide deep observations of a high-galactic latitude field in the southern continuous viewing zone. The STIS field is centered on a bright QSO at z=2.25. The observations were executed as scheduled, and no anomalies were noted. 1.2 Completed WF/PC-2 7387 (T-Tauri Star Snapshot Survey) The WF/PC-2 was used to make observations of the star HN-Tau as part of a T-Tauri class star survey. The observations were executed as scheduled, and no anomalies were noted. 1.3 Completed Two Sets of STIS/CCD 7948 (CCD Dark and Bias Monitor -- Cont. to Dec. 98) The Space Telescope Imaging Spectrograph (CCD) was used to measure CCD dark current and bias rates for the two supported amplifier settings {GAIN=1 and GAIN=4} in order to gather data for making superdarks and superbiases. The data will be used to track the growth of hot pixels on the CCD in general and within the various target acquisition apertures specifically. The observations were executed as scheduled, and no anomalies were noted. 1.4 Completed NIC/2 7329 (The Nature of the Damped LyAlpha Absorbers -- A New Study of Young Galaxies) The Near Infrared Camera (Camera Two) was used to make observations of the young galaxy/quasar Q0013-0029 in order to study the nature of its damped Lyman-Alpha Absorbers (DLAs). The DLA line systems, occasionally found in quasar spectra, provide one of only a few practical methods of detecting and studying significant numbers of galaxies at high redshifts. The observations were executed as scheduled, and no anomalies were noted. 1.5 Completed STIS/CCD/MA2/WF/PC-2/NIC/1/2/3 8076 (HDF-South Observations) The WF/PC-2, The Space Telescope Imaging Spectrograph (MA2 and CCD) and the Near Infrared Camera (Cameras One, Two and Three) all were used to make deep observations of the Hubble Deep Fields- South (HDFS-22333). This program is designed to provide deep observations of a high-galactic latitude field in the southern continuous viewing zone. The STIS field is centered on a bright QSO at z=2.25. The observations were executed as scheduled, and no anomalies were noted. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 4 Successful : 4 Scheduled Reacquisitions : 6 Successful : 6 2.2 FHST Updates: Scheduled : 5 Successful : 5 2.3 Operations Notes: The Hubble Deep Field - South (HDF-S) campaign continues through next Sunday. All HDF-S proposals operated without incident today. Using ROP SR-1, the SSR EDAC error counter was cleared four times. Per the same ROP, the SSR pointer was reset for a science data re-transmission. Per NS-3, the NSSC-1 status buffer was dumped and reset. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Continuation of normal science observations and calibrations. /DMH
