HUBBLE SPACE TELESCOPE DAILY REPORT #1112 PERIOD COVERED: 0700 EST Daily Status Report as of 097/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earthflats, Large Set) The WF/PC-2 was used to make a set of Earth flat calibration images using different filters in order to construct high quality flat fields of the OTA illumination pattern. A total of eight images were received and displayed. One image was reported to be underexposed, two were saturated, and the other five were okay. 1.2 Completed Two Sets of WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: Internal Monitor 3: Darks) The WF/PC-2 was used to obtain two 30-minute long, dark exposures to provide ongoing calibration of the CCD dark current and to monitor and characterize the evolution of hot pixels. Both images were received and displayed in the OSS. They were reported to look nominal. 1.3 Completed Two Sets of WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies) The WF/PC-2 was used to make snapshot images of radio galaxy 3C181.0 and 3C299.1 as part of a continuum survey and to study the galaxies' morphology. Two images were received and displayed. Both were reported to look nominal. 1.4 Completed WF/PC-2 5561 (WF/PC-2 Cycle 4 Calibration: Internal Monitor. 2 : Flats) The WF/PC-2 was used to make a visual flat calibration images to monitor flat field stability and the stability of the analog-to-digital converters. Five observations were monitored by the OSS. All five images were reported to be saturated. 1.5 Completed FGS 5054 (High Speed Astrometry: A Search for Planetary Companions to Low Mass Stars) The Fine Guidance Sensors were used to make observations of the position of the star Proxima Centauri to determine the presence of a Jupiter sized planet in orbit about the target star. The Baseline guide star acquisition failed to make fine lock on FGS #1 and #2. It did make course track on FGS #1. The remaining time under this guiding period was all during LOS, and could not be monitored in real time. 1.6 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4) The WF/PC-2 was used to make observations taken in parallel with the prime science observations. This is part of a survey to take pictures of a large number of fields within 30 degrees of the galactic plane. The intent is to determine the luminosity function of low mass stars and the mass density in the solar neighborhood. The observations were executed as scheduled, and no anomalies were noted. 1.7 Completed Two Sets of FGS 5134 (Extragalactic Astrometry and Astrophysics: FT12-23, Part 2 of 2) The FGSs were used to make astrometric observations of five different stars to tie the HIPPARCOS and extragalactic reference frames together. Most of the targets in this set of observations were successfully acquired and observed. Two targets failed to be located, and the Stop Flag was set. About half of the observations occurred during LOS. The observations which could be monitored were reported to be nominal. 1.8 Completed FGS 5174 (Astrometric Companion 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 science observations remains on the science tape recorder, and will be analyzed later. No anomalies were noted. 1.10 Completed WF/PC-2 5324 (Globular Cluster Core Imaging) The WF/PC-2 was used to make images of the central region of globular cluster NGC-7078 (aka, M-15). The OSS monitored the observations. The data remains on the science tape recorder. No anomalies were noted. 1.11 Completed FOS/BL 5530 (FOS Location of Spectra and Aperture) The Faint Object Spectrograph (Blue Side) was used to make Y-base maps of the FOS detectors using internal lamps. The purpose is to determine the location of the spectra on the diodes. The observations were executed as scheduled, and no anomalies were noted. 1.12 Completed WF/PC-2 5351 (Properties of Intermediate Redshift Galactic Disks Causing Damped Ly-Alpha) The WF/PC-2 was used to make observations to study the diffuse material at intermediate redshifts that is identified by absorbing Lyman-Alpha spectrum from quasar PKS0454+03. The observations were executed as scheduled, and no anomalies were noted. 1.13 Completed GHRS/1 5413 (The Local ISM Flow Within the Heliosphere) The High Resolution Spectrograph was used to make observations to study the flow of neutral atoms in the interstellar medium by observing diffuse sky background in Lyman Alpha. The observations were executed as scheduled, and no problems were noted. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 9 Successful : 8 A guide star acquisition failed to course track at 096/1632Z.
