HUBBLE SPACE TELESCOPE DAILY REPORT #1010 PERIOD COVERED: 0800 EST Daily Status Report as of 312/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WFC 5076 (WF/PC Cycle 3 Calibration: WFC Flats Wide. 2) Routine Earth flat calibration exposures were taken with the Wide Field Camera. The observations were monitored in the OSS, and six observations were received and displayed. One was underexposed, one was reported to be okay, and the others were saturated 1.2 Completed PC 5014 (WF/PC Cycle 3 Calibration: PC Flats Narrow. 2) The Planetary Camera was used to make standard Earth calibrations images for flat fielding of PC observations. Medium and narrow filters were used, with and without neutral density filters. The observations were executed as scheduled, and two observations were received and displayed. Both were reported to be saturated. 1.3 Completed PC 4929 (WF/PC Cycle 2: Improved Dark Calibration) The Planetary Camera was used to make four dark calibration images. The two exposures lasted 1200 seconds each, and the camera was pre-flashed before the observations. All four observations still remain on the science tape recorder, and will be analyzed later. 1.4 Completed FOS/RD 3448 (Ultraviolet Evolution of Elliptical Galaxies at Moderate Redshifts) The Faint Object Spectrograph (Red Side) was used to to make three ultraviolet observations of the high red shifted elliptical galaxy A1758-7 to look for changes in the "UV rising branch". This feature is expected to change rapidly with the redshift of the galaxy, and should provide information on the hot stars which are believed to produce it. The observations were monitored in the OSS, and the data quality was assessed. The peakups for the first two observations had nearly identical counts in each group, so even though each observation chose a point to peakup on, that point differed little from its neighbors. The target was very extended. The third observation still remains on the science tape recorder, and will be analyzed later. 1.5 Completed PC/WFC 5026 (WF/PC Cycle 3 Calibration: Rapid Internal Monitor) The Wide Field Camera and the Planetary Camera were used to make two internal flat calibration images. These images will be used to look for measles and daisies (i.e., different forms of contamination), and to monitor scattered light. The observations were executed as scheduled, and both observation are still on the science tape recorder. 1.6 Completed Four Sets of WFC 4381 (HST Medium - Deep Survey - Cycle 3) The Wide Field Camera was used to make two sets of medium-deep high latitude sky survey observations taken in parallel with the prime science observations. The observations were executed as scheduled, and no problems were reported. 1.7 Completed GHRS/2 4536 (The Distance of High - Velocity Clouds: Cycle 3 High) The High Resolution Spectrograph was used to make observations of quasars PG0906+597 and PG0859+533 to obtain spectra about the Mg H and K lines. These objects are expected to lie in front of a high velocity cloud. It is hoped that the distance and the velocity of this cloud can be found. The OSS monitored the observations, and assessed the data quality. No anomalies were reported. 1.8 Completed GHRS/2 4869 (Spectroscopy of Interacting Binaries - 4185, Cycle 3 High) The High Resolution spectrograph was used to make six observations of the interacting binary star V-Sge. IUE spectra showed the possible presence of red-shifted emission at a velocity of about 700 Km/Sec. This suggests a major mass transfer event is in process. The target was successfully located. The wavelength calibrations and spectral observations were received and displayed. All six observations were reported to look okay. 1.9 Completed WFC 4348 (Long Period Variables of M81: Cycle 3 Medium) The Wide Field Camera was used to make one image to the galaxy M-81 (aka, NGC-3031) to look for long period variable stars which can be compared to those already studied in our own galaxy and the Magellanic Clouds. These stars should have period of from 100 to 100 days. The observation was reported to look okay. 1.10 Completed HSP/UV2 1093 (Observations of ZZ Ceti Stars) The High Speed Photometer was used to make ultraviolet observations of G117-B15A which is a pulsating white dwarf with a period of 215 seconds. and has a visual magnitude of 15.2 . Two ultraviolet observations were made to obtain the star's color (i.e., temperature) as a function of time. The onboard target acquisition was successful. Both observations were reported to look satisfactory. 1.11 Completed PC 4904 (The Nuclei of Nearby S0 and Spiral Galaxies - III A PC Snapshot Image) The Planetary Camera was used to make one observations of the low-red-shift galaxy NGC-3769 to study its surface brightness profile, identify sub-arc-second scale condensations, find point sources, and look for gasious disk and dust lanes. The observation was executed without problems. The data was received and displayed. No problems were reported. 1.12 Completed HSP/UV1 4810 (Constraints on Continuum Models of Active Nuclei: Fast Ultraviolet) The High Speed Photometer was used to make ultraviolet observations of the Seyfert galaxy NGC-4051. This galaxy has rapid variations in its active nuclei at X-Ray as small as 100 seconds. The target acquisitions left the target well centered. Two observations were received and displayed. No anomalies were reported. 1.13 Completed FOS/RD 4212 (Internal Wavelength Calibration) The Faint Object Spectrograph was used to make wavelength calibration observations for every disperser-detector combination, to monitor the stability of the FOS wavelength scale. A total 19 observations were made. They all were received and displayed. No anomalies were noted. 1.14 Completed FOS/RD 3791 (Quasar Absorption Line Survey: Cycle 2 Observations) The Faint object Spectrograph (Red Side) was used to make observations of quasar PKS0003+15. This is a continuation of proposal FOS 2424. The target was reported to be well centered. The observations were reported to be okay. 1.15 Completed WFC 5013 (WF/PC Cycle 3 Calibration: WFC Flats Narrow. 2) The Wide Field Camera was used to make four Earth flat calibration images to be used for flat fielding of WFC observations. The observations used the narrow band filters, both with and without neutral density filters. A total of four observations were received. All four observations were reported to be okay. 1.16 Completed PC 5072 (WF/PC Cycle 3 Calibration: PC Flats wide. 1) Both the Wide Field Camera and the Planetary camera were used to make Earth Flat calibration exposures using the wide and medium band filters. Six observations were received and displayed in the OSS. Five observations were reported to be saturated. One observation was reported to look okay, but 15 segments were missing. The DCF has requested an LOR to see if the missing data can be recovered. 1.17 Completed FGS 4893 (Orbital Motions of Close Binary Stars: Cycle 3 High) Fine Guidance Sensor #3 was used to make astrometric observations of the binary star system HD32923 to obtain its orbital elements. These observations are important since most of the estimates of stellar mass are made by observing elements of these systems. The astrometry was monitored and no problems were seen in the telemetry. 1.18 Completed PC 4308 (Snapshot Survey for Companions to Planetary Nebula Nuclei - Cycle 3 High) The Planetary Camera was used to make an observation of the central region of planetary nebula EGB5. It is possible that the central star in a double star. The observation still remains on the science tape recorder, and will be analyzed later. No anomalies were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 18 Successful : 17 The Guide Star acquisition at 309/1507Z failed on secondary FGS #@ on its first attempt.

The DF-224 automatically switched to MSS#2. The unit reported lower than normal temperatures during this period, and was in the shadow of a High Gain Antenna. The project had previously decided to switch to the Magnetic Field Model should an MSS Channel Saturate for more than three hours. The Ground System uplinked and initiated a Mag-Field Model in the spacecraft. The anomaly is being investigated. An on-orbit test of the Magnetic Field Model was conducted in June 1993. The MSS#1 V2 channel has since returned to a normal signature. 4.2 Significant Unresolved Anomalies: None 5.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH -END-
