HUBBLE SPACE TELESCOPE DAILY REPORT #1690 PERIOD COVERED: 0000Z (UTC) 08/05/96 - 0000Z (UTC) 08/06/96 Daily Status Report as of 219/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WF/PC-2 6346 (Snapshot Survey of the Ultraluminous IRAS = Galaxy Sample-Part 1 High) The WF/PC-2 was used to make snapshot survey observations of the = ultraluminous IRAS galaxy IR12450+34. These data will be searched for = multiple cores, which imply a merger has occurred, and for starburst = regions. The observations were executed as scheduled, and no anomalies = were noted. 1.2 Completed FOC/96 6775 (Secular Changes in the Jet of M87) The Faint Object Camera (F/96) was used to look for secular changes= in the jet coming out of the active galactic nuclei of Galaxy M-87. = M-87 is a large (Ep Class) elliptical galaxy located in the Virgo = galactic cluster. Comparison with images taken in previous observing = cycles will allow the investigators to measure changes in the jet, and = the speed of various knots in the jet. Polarization images were also = taken. The observations were executed as scheduled, and no anomalies = were noted. 1.3 Completed FGS 6495 (The Mass of the Bright Giant HD173764) The FGSs were used to make astrometric observations of bright, = spectrographic binary system, giant star HD173764. This binary system = has a 832 day period. The objective is to determine the individual = masses of the G4 and B9 class pair. The observations were completed as = scheduled, and no anomalies were noted. 1.4 Completed GHRS/2 6078 (The Wind Momentum-Luminosity Relationship = for SMC A and B Supergiants.) The High Resolution Spectrograph (Side Two) was used to make = spectrographic observations of the O/B class stars AV315 and AV415 which = are located in the Small Magellanic Cloud in order to measure the wind = momentum-luminosity relationship in these low metallicity stars. This = relationship is used to determine the distance to galaxies. The observati= ons were completed as planned and no problems were reported. 1.5 Completed GHRS/2 6511 (A Search for Outflows and Mass Loss From = Population II Red Giants) The High Resolution Spectrograph (Side Two) was used to make high = signal-to-noise ratio spectrographic observations of the population II, = red, giant star HD216143 in order to search for out flows and mass loss = from the star. This is done by making measurements of the H and K lines = of Mg. These lines are sensitive to mass motion in the choromosphere. A = wavelength calibration image was also taken. The observations were = completed as planned, and no anomalies were reported. 1.6 Completed WF/PC-2 6353 (A Snapshot Emission Line Imaging Survey of = Very Low Excitation Planetary Nebulas) The WF/PC-2 was used to make snapshot observations as part to an = emission line survey of the very low excitation planetary nebula = PK100-08D1 (Class PNe). This target was selected based on the O III/H = alpha line flux ratio. The observations were executed as scheduled, and = no anomalies were noted. 1.7 Completed GHRS/1 6544 (Dwarf Novae in Quiescence) The High Resolution Spectrograph (Side One) was used to make = moderate resolution, high signal-to-noise ratio spectrographic = observations of the dwarf, quiescent nova WX-Hyi. The intent is to study = the accretion disk in the system in order to determine if x-ray = photoionization of the disk produces the ultraviolet lines and the = underlying continuum. The observations were completed 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 : 13 Successful : 13 2.3 Operations Notes: There were no reported operational problems. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH
