HUBBLE SPACE TELESCOPE DAILY REPORT #2142 PERIOD COVERED: 0000Z (UTC) 06/10/98 - 0000Z (UTC) 06/11/98 Daily Status Report as of 162/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed STIS/CCD 7926 (CCD Dark and Bias Monitor -- Continued) The Space Telescope Imaging Spectrograph (CCD) was used to make several dark and bias calibration observations. This is to measure CCD dark current and bias rates for the two supported amplifier settings {gain = 1 and gain = 4} in order to gather data for making superdarks and superbiases. These observations will also track the growth of hot pixels on the CCD in general and within the various target acquisition apertures specifically. The observations were executed as scheduled, and no anomalies were noted. 1.2 Completed NIC/1 7821 (SINS: The Supernova Intensive Study - Cycle 7+: Scarlet SINS) The Near Infrared Camera (Camera One) was used to make observations of the super nova LMC-SN1987 which is located in the Large Magellanic Cloud. Supernovae create the chemical history of the Universe, energize the interstellar gas, and stand at the center of efforts to understand the extragalactic distance scale. The observations were completed as scheduled, and no problems were noted. 1.3 Completed STIS/CCD 7912 (STIS Parallel Archive Proposal - Nearby Galaxies - Imaging and Spectroscopy) The Space Telescope Imaging Spectrograph (CCD) was used to make parallel observations of nearby galaxies. This survey will be useful to study the star formation histories, chemical evolution, and distances to these galaxies. These data will be placed immediately into the Hubble Data Archive. The observations were completed as scheduled, and no problems were reported. 1.4 Completed Seven Sets of STIS/CCD 7908 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal) The Space Telescope Imaging Spectrograph (CCD) was used to make calibration observations as part of the POMS Test Proposal. This was a STIS non-scripted parallel proposal. The observations were completed as planned, and no problems were reported. 1.5 Completed WF/PC-2 8049 (Long WF/PC-2 Decontaminations during 2nd NIC/3 Campaign) The WF/PC-2 was used to make long decontamination procedures as part of the second NIC/3 campaign. Each decon is followed by five 30-minute darks. During this time, no external science WF/PC-2 observations were executed. The decontaminations were executed as scheduled, and no anomalies were noted. 1.6 Completed STIS/CCD 7645 (STIS FUV-MAMA Cycle 7 Flats) The Space Telescope Imaging Spectrograph (CCD) was used to make far-ultraviolet flat calibration images. This program will obtain FUV-MAMA flat-field observations with the Kr lamp for the construction of on-orbit D-flats for G140M. A dark calibration image was also taken. The observations were completed as planned, and no anomalies were reported. 1.7 Completed NIC/1/2/3 7245 (Galaxy Evolution in Rich Clusters) The Near Infrared Camera (Cameras One, Two and Three) was used to make observations of the galactic cluster Abell1795. The purpose is to study the morphological and spectral evolution of galaxies within this cluster environment. A dark calibration image was also taken. The observations were completed as planned, and no problems were reported. 1.8 Completed Two Sets of NIC/1/2/3 7871 (The Properties of High Redshift Galaxies : A Near-Infrared Redshift Survey) The Near Infrared Camera (Cameras One, Two and Three) was used to make infrared galactic survey observations of high redshifted galaxies in s sky field designated as Field-1417. A comparison between the population of galaxies in the low {z<1} and high {z>2} redshift universe has shown that the peak era of star forming activity in the universe occurs in the redshift interval 1
