It is possible that this galaxy is at the far edge of the local = supercluster, and thus at the edge of the large void between the local = supercluster and the Perseus-Pisces supercluster.

The observations were executed as scheduled, and no = anomalies were noted. 1.7 Completed GHRS/2 6530 (The Wind Momentum: Luminosity Relationship = for LMC A and B Supergiants) The High Resolution Spectrograph (Side Two) was used to make = spectrographic observations the A/B class, supergiant star HD269651 which = is located in the Large Magellanic Cloud. These data are part of a large = effort to calibrate the wind momentum-luminosity function for supergiant = stars. The observations were completed as planned, and no problems were = reported. 1.8 Completed Two Sets of WF/PC-2 6741 (Synoptic Monitoring of = Seasonal Phenomena on Mars) The WF/PC-2 was used in the rapid mode to make observations of the = surface and meteorological changes on the planet Mars in order to do = synoptic monitoring of its seasonal phenomena. Special attention will be = given to the Ares Valley region, which is intended as a landing site for = the Mars Pathfinder mission. The observations were completed as planned, = and no problems were reported. 1.9 Completed GHRS/1 6558 (The Accreting Magnetic White Dwarf in AM = Her, Heating and Chemical Composition) The High Resolution Spectrograph (Side One) was used to make = spectrographic observations of the accreting, magnetic, binary system, = white dwarf AM-Her in order to study its heating function and chemical = composition. The objective is to study the physics of the accretion in = great detail. A wavelength calibration image was also taken. The = observations were completed as planned, and no anomalies were reported. 1.10 Completed FOS/BL 6799 (The BAL Region Covering Factor in a Sample = of IRAS-Selected QSOs) The Faint Object Spectrograph (Blue Side) was used to make = spectrographic observations of QSO IR0345+005 in order to determine the = criteria by which the presence of BALs in the spectra may be predicted. = During the execution of this proposal, FOS status buffer messages were = received indicating that there was an FOS target acquisition failure at = 004/092423Z. HSTAR 5866 was written. Otherwise, the observations were = completed, and no further problems were reported. 1.11 Completed WF/PC-2 6802 (Cosmology with The Medium Deep Survey) The WF/PC-2 was used to make observations in parallel with the = prime science observations as part of the Medium Deep Survey.
