HUBBLE SPACE TELESCOPE DAILY REPORT #1567 PERIOD COVERED: 0000Z (UTC) 02/08/96 - 0000Z (UTC) 02/09/96 Daily Status Report as of 040/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WF/PC-2 6189 (WF/PC-2 Cycle 5 Calibration: Internal = Monitor - Visual Flats) The WF/PC-2 was used to make internal visual flat calibration = images. Both photometric and narrow-band filters were used. The = observations were executed as planned, and no problems were reported. 1.2 Completed GHRS/2 5875 (Hot Winds in T-Tuari Stars) The High Resolution Spectrograph (Side Two) was used to make = observations of the T-Tauri class star DG-Tau in order to study its hot = winds. This star is known to have one diskless pre-main sequence star as = a companion. A wavelength calibration image was also taken. The = observations were executed as scheduled, and no anomalies were noted. 1.3 Completed Two Sets of S/C 6843 (Test of Technique to Avoid FGS1 = Stalls) Special test were conducted using FGS #1 to test a technique for = avoiding FGS stalls. The observations were completed as scheduled, and no = anomalies were noted. 1.4 Completed WF/PC-2 5931 (Location of Particle Acceleration in Radio = Hot Spots) The WF/PC-2 was used to make signal to noise images of 3C111-East = to study the location of particle acceleration in its radio hot spots. = Radio hot spots are just one of many locations where active galactic = nuclei (AGN) phenomena imply the presence of ultra-relativistic particles. = The observations were completed as scheduled, and no problems were = reported. 1.5 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat) The WF/PC-2 was used to make Earth streak flat calibration images. = These streak flats will be used to produce flat fields, to map the OTA = illumination pattern and, in combination with other data, to produce new = superflats. The observations were completed as planned, and no problems = were reported. 1.6 Completed WF/PC-2 6184 (WF/PC-2 Cycle 5 Photometric Calibration = Monitor UV/OPT STD) The WF/PC-2 was used to make ultraviolet and optical observations = of standard star GRW+70D582 in order to monitor the photometric = calibrations of the camera and to check for decontamination. The = observations were executed as scheduled, and no anomalies were noted. 1.7 Completed Three Sets of WF/PC-2 6179 (WF/PC-2 Cycle 5: Photometric = Zero Point) The WF/PC-2 was used to make observations of photometric standard = star GRW+70D582 in order to calibrate the photometric zero point. The = calibration was done for eighteen WF/PC filters. The observations were = executed as planned, and no problems were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 7 Successful : 7 Scheduled Reacquisitions : 8 Successful : 8 2.2 FHST Updates: Scheduled : 17 Successful : 17 2.3 Operations Notes: ESTR #2 remains powered off. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH
