HUBBLE SPACE TELESCOPE DAILY REPORT #1810 PERIOD COVERED: 0000Z (UTC) 02/05/97 - 0000Z (UTC) 02/06/97 Daily Status Report as of 037/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WF/PC-2 6348 (Blue Continuum Snapshots of 3CR Radio = Galaxies) The WF/PC-2 was used to make some snapshot images of the blue = continuum in radio galaxy 3C15.0. Combined with existing data, these = exposures will provide high spatial resolution information on the color = distribution within galaxies, redding due to dust, spacial indices of the = optical synchrotron jets, and colors of the active nuclei and tidal jets. = The observations were executed as scheduled, and no anomalies were = noted. 1.2 Completed FOS/RD 6592 (The Distribution and Evolution of = Lyman-Alpha Forest Cloud Sizes) The Faint Object Spectrograph (Red Side) was used to make = observations of quasi-stellar source Q0107-025B in order to study the = distribution and evolution of the foreground Lyman-Alpha Clouds. = Together with ground-based observations, these data will help study the = evolution of the cloud's radii with redshift, with the characteristic = size of the Lyman-Alpha absorbers decreasing with increasing redshift. = The observations were executed as scheduled, and no anomalies were noted. = 1.3 Completed WF/PC-2 7202 (The WF/PC-2 B Band Parallel Survey: A = Systematic and Synoptic Study of Galaxy Formation and Evolution - Short = Orbit Case) The WF/PC-2 was used to make observations as part of a B-Band = Survey to make synoptic study of galaxy formation and evolution. These = observations were taken in parallel with the prime science observations. = They were completed as planned, and no anomalies were reported. 1.4 Completed WF/PC-2 6906 (WF/PC-2 Cycle 6 Calibration: Internal = Monitor-Visual Flats) The WF/PC-2 was used to make internal calibration visual flat = images as part of the Cycle 6 internal monitoring of the instrument's = operations. This proposal defines the standard series of internal flat = fields, which will be executed twice per month. At 036/1219Z, about = one-half hour before the end of this proposal, the scheduled FHST update = was not successful. Otherwise, the observations completed as planned, = and no effect on science was reported. 1.5 Completed GHRS/2 6210 (GHRS Spatial PSF Characterization - Cycle = 5) The High Resolution Spectrograph (Side Two) was used to make = observations of standard star HD106343 as part of a Cycle 5 spatial point = spread function characterization using the small science aperture. This = is to study and evaluate the scattering of light contributed by objects = within 3 arcseconds of the GHRS's aperture. The observations were = completed as planned, and no problems were reported. 1.6 Completed WF/PC-2 6902 (WF/PC-2 Cycle 6 Photometric Calibration = Monitor UV/OPT STD) The WF/PC-2 was used to make both ultraviolet and optical = photometric observations of the standard star GRW+70D582 as part of a = Cycle 6 calibration procedure. This observations was done immediately = before and after decontamination procedures. The observations were = completed as planned, and no problems were reported. 1.7 Completed WF/PC-2 6419 (Testing Unified Models With a Complete = Sample of Seyfert Galaxies) The WF/PC-2 was used to make observations of the Seyfert galaxies = Mark620 and NGC3081 to help build a complete survey of the Seyfert class = of galaxies. This will help test the current model for Seyfert class = galaxies. This model proposes that all Seyferts have a Seyfert-1 = nucleus, which is surrounded by a torus of gas and dust. The = observations were completed as planned and no anomalies were noted. 1.8 Completed WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: Earth Flats The WF/PC-2 was used to make observations of the bright Earth to = obtain streak flats which are used to construct high quality flat fields = for the WF/PC-2 filter set. The observations were executed as scheduled, = and no anomalies were noted. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 8 Successful : 8 Scheduled Reacquisitions : 12 Successful : 12 2.2 FHST Updates: Scheduled : 11 Successful : 10 The update at 036/1219Z was not sucessful. 2.3 Operations Notes: There were no significant operational problems. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH
