HUBBLE SPACE TELESCOPE DAILY REPORT #2054 PERIOD COVERED: 0000Z (UTC) 02/04/98 - 0000Z (UTC) 02/05/98 Daily Status Report as of 036/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental Darks PT1/3) The WF/PC-2 was used to make supplemental dark calibration images. This set of calibrations is intended to obtain three dark frames every day to provide data for monitoring and characterizing the evolution of hot pixels. The observations were executed as scheduled, and no anomalies were noted. 1.2 Completed FOC/96 6930 (FOC Neutral Density Filter Calibrations) The Faint Object Camera (f/96) was used to observations of NGC-5139 to make neutral density filter calibration observations. Observations of the core of R136A will provide a wide-range of magnitudes and a large number of stars for the analysis, along with direct comparison with previous calibrations done at different wavelengths. An internal flat and a dark calibration image were also taken. The observations were completed as planned, and no anomalies were reported. 1.3 Completed Two Sets of NIC/2/3 7907 (NICMOS Pure Parallel Winter 97-98) The Near Infrared Camera (Cameras Two and Three) was used to make pure parallel spectrographic observations of sky regions when another instrument is prime. The observations were completed as planned, and no anomalies were reported. 1.4 Completed NIC/1/2/3 7246 (Line Imaging of the L1448-Star Shock Region) The Near Infrared Camera (Cameras One, Two, and Three) was used to make observations of the star shock region of L1448-4. The bow shock associated with this infrared source star is one of the best examples of the interaction of an outflow from a recently formed star with the surrounding medium. The observations were executed as scheduled, and no anomalies were noted. 1.5 Completed STIS/CCD 7803 (Daily Darks to Update Acquisition Bad Pixel Table Part III) The Space Telescope Imaging Spectrograph (CCD) was used to make daily dark calibration updates. These daily darks are intended to identify hot pixels for update to the acquisition on-board FSW hot pixel table. Daily hot pixel lists can also be used for science data analysis. The observations were completed as planned, and no anomalies were reported. 1.6 Completed STIS/CCD 7910 (STIS Extragalactic Parallel Survey) The Space Telescope Imaging Spectrograph (CCD) was used to make extragalactic slitless spectrographic observations as part of the parallel high galactic latitude survey to search for emission line galaxies. Data was taken in parallel, and not subject to proprietary time. The observations were executed as scheduled, and no anomalies were noted. 1.7 Completed STIS/CCD 7672 (STIS CCD Sensitivity Monitor) The Space Telescope Imaging Spectrograph (CCD) was used to make observations of standard star AGK+81D266 in order to monitor the sensitivity of each CCD grating mode to detect any change due to contamination or other causes. A wave length calibration image was also taken. The observations were completed as scheduled, and no anomalies were noted. 1.8 Completed STIS/CCD 7672 (STIS CCD Sensitivity Monitor) The Space Telescope Imaging Spectrograph (CCD) was used to make observations of standard star UZ-Tau in order to monitor the sensitivity of each CCD grating mode to detect any change due to contamination or other causes. The observations were completed as scheduled, and no anomalies were noted. 1.9 Completed STIS/CCD 7911 (STIS Galactic Plane Pure Parallel Program) The Space Telescope Imaging Spectrograph (CCD) was used to make low galactic latitude survey observations in parallel with the prime science observations. Short exposures with the 50CCD imaging mode will provide the wavelength zero-point calibration. These data will be placed immediately into the Hubble Data Archive. The observations were executed as scheduled, and no anomalies were noted. 1.10 Completed STIS/CCD/WF/PC-2 7367 (Multi-wavelength Imaging of Circumstellar Disks in the Orion Nebula) The Space Telescope Imaging Spectrograph (CCD) and the WF/PC-2 was used to make multi-wavelength imaging of circumstellar disks (NGC-1976) seen as silhouettes against the bright emission-line background in the Orion Nebula. With these data one should be able to examine the radial structure of the disks in great detail, and over a wide spatial extent. The observations were completed as planned, and no problems were reported. 1.11 Completed WF/PC-2/STIS/CCD/NIC/1/2 7307 (The Formation and Evolution of Rich Star Clusters in the LMC) |10| The WF/PC-2, the Space Telescope Imaging Spectrograph (CCD), and the Near Infrared Camera (Cameras One and Two) were used to make observations of the rich star cluster H14-Cen which is located within the Large Magellanic Cloud in order to study their formation and evolution. These observations will help us understand the origin and evolution of rich star clusters in our own Galaxy. The observations were complete as scheduled, and no anomalies were reported. 1.12 Completed NIC/1/2/3 7819 (A New Stellar Generation in 30 Doradus) The Near Infrared Camera (Cameras One, Two and Three) was used to make observations of the 30-Doradus nebula. There is ample evidence for current star formation within this nebula, which appears to have been triggered by the massive central cluster {R136}, in and just beyond the curved nebular filaments surrounding it. The observations were executed as scheduled, and no anomalies were noted. 1.13 Completed STIS/CCD 7739 (Star Formation in the Prototype Super Star Cluster R136) The Space Telescope Imaging Spectrograph (CDD) was used to study the star formation in the prototype super star cluster R136. Similarly extreme objects have now been recognized in more distant galaxies, and may in fact be the young analogs of globular clusters. Several offset images and a wave length calibration image were also taken. The observations were completed as planned, and no anomalies were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 10 Successful : 10 Scheduled Reacquisitions : 1 Successful : 1 2.2 FHST Updates: Scheduled : 15 Successful : 15 2.3 Operations Notes: Operations personnel report that the NCC network is connected to the IP SCUD as of 035/2136Z. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Continuation of normal science observations and calibrations. /DMH
