HUBBLE SPACE TELESCOPE DAILY REPORT #1457 PERIOD COVERED: 0000Z (UTC) 08/17/95 - 0000Z (UTC) 08/18/95 Daily Status Report as of 230/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WF/PC-2 6137 (A Search for Brown Dwarfs and Luminous Young Planets in the Hyades) The WF/PC-2 was used to make observations of M class star RHY240 which is located in the Hyades cluster looking for planetary and brown dwarf companions. The observations were executed as scheduled, and no anomalies were noted. 1.2 Completed GHRS/2 5885 (GHRS - Observations of Candidate Beta-Pictoris Circumstellar Gaseous Disks) The High Resolution Spectrograph (Side Two) was used to make observation of star HD42111 which is a candidate to have a Beta Pictoris-like gaseous disks. The objective is to confirm the existence of circumstellar gas, and to understand its origin. The observations were completed as planned, and no anomalies were reported. 1.3 Completed WF/PC-2 5849 (Host Galaxies of Luminous Nearby Quasars) The WF/PC-2 was used to make deep exposure observations of host galaxy PG1444+407 which is known to have a luminous nearby quasar. The observations were executed as scheduled, and no anomalies were noted. 1.4 Completed FOS/BL 5948 (Damped Lyman Alpha Absorption Lines in Moderate Redshifted Galaxies) The Faint Object Spectrograph (Blue side) was used to make observations of the moderate redshift galaxy PG1329+412 to study its damped Lyman Alpha absorption lines. The observations were executed as scheduled, and no anomalies were reported. 1.5 Completed WF/PC-2 6189 (WF/PC-2 Cycle 5 Calibration: Internal Monitor - Vis Flats) The WF/PC-2 was used to make internal visual flat calibration images. Both photometric and narrow-band filters were used. The observations were executed as planned, and no problems were reported. 1.6 Completed WF/PC-2 6294 (Determination of the Extragalactic Distance Scale) The WF/PC-2 was used to make observations of galaxy NGC-7331 to measure the period of individual Cepheid stars to determine the extragalactic distance scale. The observations were executed as scheduled, and no anomalies were noted. 1.7 Completed Two Sets of FOS/RD 6236 (FOS Cycle 5: Location of Spectra and Wavelength Calibration: Red Side Detector) The Faint Object Spectrograph (Red Side) was used to make calibration observations in order to determine the location of the spectra and to perform a wavelength calibration. All observations were internal. The observations were completed as planned, and no anomalies were reported. 1.8 Completed WF/PC-2 5957 (Snapshot of 3CR Radio Galaxies) The WF/PC-2 was used to make observations for radio galaxy 3C55.0 to study the morphology of the radio galaxy. The observations were executed as scheduled, and no anomalies were noted. 1.9 Completed WF/PC-2 5913 (Low Mass Binaries and the Luminosity Function. ) The WF/PC-2 was used to make observations of the low mass binary star system MT010 (a late-type M class dwarf) to study the local stellar luminosity function. The observations were executed as scheduled, and no anomalies were noted. 1.10 Completed GHRS/1 5738 (The Stellar Content of Wolf- Rayet Galaxies) The High Resolution Spectrograph (Side One) was used to make spectrographic observations of the knots and stellar content of Wolf-Rayet galaxy NGC-1741-B. This galaxy exhibits a broad HeII 4686 A0 emission that is stellar in origin. A wavelength calibration was also taken. The observations were completed as planned, and no problems were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 3 Successful : 3 One acquisition at 229/100321Z failed to coarse track when the scan step limit was exceeded. HSTAR 5252 describes this event. HSTAR 5253 documents an approximate 4 minutes loss of lock at 230/005600Z. Scheduled Reacquisitions : 14 Successful : 14 2.2 FHST Updates: Scheduled : 4 Successful : 4 2.3 Operations Notes: At 229/1900Z, realtime operations returned to the STOCC from the SAMS backup facility. The equipment has operated without fault since that time. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH -END-
