HUBBLE SPACE TELESCOPE DAILY REPORT #876 PERIOD COVERED: 0800 EST Daily Status Report as of 119/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed PC 2944 (Internal Velocity Distribution in Globular Clusters Part Two) The Planetary Camera was used to make observations of globular cluster NGC-104 (aka, 47 Tucanae) at five core radii from its center to study its internal velocity dispersion. The baseline guide star acquisition failed, and the shutter did not open for the first observation. The reacquisition also failed and the remainder of the observation did not occur. It was thought that the secondary guide star is 0.5 magnitude fainted than originally thought. (See Note 2.1) 1.2 Completed FOC/96 4821 (Magellanic Cloud Planetary Nebulae: Cycle 3 Med) The Faint Object Camera (f/96) was used to make one high resolution image with filter F501N of the planetary nebula LMC-WS12 which is located in the Large Magellanic Cloud. This observation is to help determine its mass and age. The observations was reported to look fine. 1.3 Completed FOC/96 4075 (Magellanic Cloud Planetary Nebulae: Cycle 2 Med) The Faint Object Camera (f/96) was used to make one high resolution image with filter F501N of the planetary nebula SMC-N4 which is located in the Small Magellanic Cloud. This observation is to help determine its mass and age. The observations was reported to look fine. 1.4 Completed WFC 1297 (GTO High Latitude Parallel Program) The Wide Field Camera was used to make two long exposure high latitude observations which were taken in parallel with the prime science observations. Both observations were reported to be satisfactory. 1.5 Completed GHRS/2 3943 (Local Interstellar Medium and D/H Ratio - Cycle 2) The High Resolution Spectrograph was used to try and make a spectral observation of Lyman Alpha emission in the star Alpha Centauri (aka, HD128621) to observe interstellar H and D line in absorption against the stellar emission feature. The onboard acquisition for this series of observations failed. A position correction was uplinked in real-time, but to no avail. The science observations was nearly blank. 1.6 Completed FOS/BL 4054 (Probing the Nuclear Regions of Seyfert Galaxy NGC-5548) The Faint Object Spectrograph was used to make spectral observations of Seyfert galaxy NGC-5548 to study time variability in its continuum, and emission lines in Carbon IV and Helium II. The observations were executed as scheduled, and no problems have been reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 5 Successful : 4 118/1528Z, Secondary star was not acquired, attitude error does not appear to be a problem. Threshold counts too low. (See Note 1.1) Scheduled Reacquisitions : 10 Successful : 8 118/1704Z, and 1840Z, related to previous acquisition failure. Subsequent observations okay. (See Note 1.1) Losses of Lock : 0 2.2 FHST Updates: Scheduled : 5 Successful : 5 2.3 Significant HSTARs: None 2.4 Operations Note: None 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete WFC 4105 (HST Medium Deep Survey: Cycle 1 High Latitude) 3.2 Complete FOS/RD 3858 (The Inner Regions of Quasars: Cycle Two Continuation) 3.3 Complete WFC 4105 (HST Medium Deep Survey: Cycle 2 High Latitude) 3.4 Complete Two Sets of PC 4770 (WF/PC Cycle 2 Calibration: Internal Monitor Proposal) 3.5 Complete FOC/96 3801 (Search for QSOs Suitable for Subsequent Observations of He II) 3.6 Complete Five Sets PC 4714 (WF/PC Cycle 2 Calibration: PC Internal Delta Flats) 3.7 Complete Four Sets of FOC/96 4804 (UV Imaging of Nearby Galaxies With FOC/96) 3.8 Complete FOS/BL 4054 (Probing the Nuclear Regions of Seyfert Galaxy NGC-5548) 3.9 Uplink Updated Ephemeris Tables, Per MOSES 2871 3.10 Complete WFC/PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor) 4.0 ANOMALY STATUS: 4.1 Significant New Anomalies: None 4.2 Significant Unresolved Anomalies: None 5.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH -END-
