HUBBLE SPACE TELESCOPE DAILY REPORT #942 PERIOD COVERED: 0800 EST Daily Status Report as of 215/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed FOS/BL 4468 (Ultraviolet Spectropolarimetry of AG Car in its Current Outburst Cycle ) The Faint Object Spectrograph was used to make observations of the variable star AG Carine (aka, HD94910) and the standard polarization standard star BD+64D106. AG Carine is known to have outburst about once every 15 years during which the mass loss rate increases significantly. The peakup stopped cold after the ninth dwell point, and five status buffer error messages were output. At the same time the WFPC was undergoing a flash decontamination procedure, and output an error of its own. Engineers were called in both at the OSS and MOR. As of this writing, the problem seems to have been that a minor frame pulse didn't get to the instruments. Further analysis is continuing. The subsequent peakups were executed without problems. But the counts indicated the target was not well centered. The following polarization observation was received and displayed. The counts were fairly high. A recentering event occurred during the next science observation, but the jitter did not seem unusually high. The next two science observations looked good, but it appeared as if the target was not well centered in the aperture. During a later observation, a loss of lock prevented the shutter from opening. The current flight software caused the shutter to remain closed for the entire duration. As a result, no observations were obtained for this proposal. An HSTAR was written. 1.2 Completed FOS/RD 4396 (QSO Absorption System Snapshot Survey - Part 1 of 3: Cycle 3 High) The Faint Object Spectrograph (Red Side) was used to make one spectrographic observation of quasar 0355-4820 to look for absorption line systems at low red shift, emission lines, and to study the QSO's continuum. The observation was executed as scheduled, and no problems were reported. 1.3 Completed FOS/BL 4976 (UV Rotation Light Curves for Pluto, and Charon's UV Spectrum - Split) The Faint object Spectrograph was used to make a TALED exposure subsequent to other spectral observations of the planet Pluto and its moon Charon. After a corrective SIP maneuver was uplinked to the spacecraft, spectral observations were made of the planet Pluto. The observations were executed in fine lock. No problems were reported. 1.4 Completed WFC/PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor) Rapid Internal Monitoring observations were made with both the Wide Field Camera and the Planetary Camera using filter F555W to look for new forms of contamination (i.e. daises and measles), and the possible return of quantum efficiency hysteresis. The observations were monitored in the OSS, and the data quality was assessed. No problems were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 4 Successful : 4 Scheduled Reacquisitions : 8 Successful : 8 Losses of Lock : 1 Loss of lock at 215/0049Z reacquisition.
