HUBBLE SPACE TELESCOPE DAILY REPORT #1566 PERIOD COVERED: 0000Z (UTC) 02/07/96 - 0000Z (UTC) 02/08/96 Daily Status Report as of 039/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed FOS/RD 6091 (Ionization and Abundances of BALQSOs) The Faint Object Spectrograph ( Red Side) was used to make = observations of BALQSO 1524+5147 in order to study it ionization and = abundances. This QSO is known to show broad absorption lines in its = spectra. The goal is to observe lines from several different ionization = states of Oxygen. The observations were completed as planned, and no = anomalies were reported. 1.2 Completed Two Sets of WF/PC-2 5999 (The Nuclear Structure of S0 = Galaxies: A PC Imaging Survey) The WF/PC-2 was used to make observations of S0 class galaxy = NGC-3870 in order to study its nuclear structure. This is a part of a = large survey of S0, E/S0, and S0/a class galaxies. The targets will cover = a wide range in luminosity and environment. The observations were = completed as planned, and no anomalies were noted. 1.3 Completed FOS/BL 5515 (Eclipse Mapping of the Touchstone Systems = CM-Dra Cycle 4 Medium) The Faint Object Spectrograph (Blue Side) was used in the Rapid = Mode to make observations of the Touchstone System CM-Draconis (aka, = GL630.1) to do eclipse mapping. The objective is to map the upper = atmosphere of the M4Ve class component of CM Dra by measuring the = disappearance of light during the eclipse of the secondary. The = observations were completed as scheduled, and no anomalies were noted. 1.4 Completed Two Sets of S/C 6843 (Test of Technique to Avoid FGS1 = Stalls) Special tests were conducted using FGS #1 to test a technique for = avoiding FGS stalls. The observations were completed as scheduled, and no = anomalies were noted. 1.5 Completed WF/PC-2 5972 (Determination of the Extragalactic Distance = Scale) The WF/PC-2 was used to make observations of the galaxy NGC-2090 = looking for standard candle Cepheid variable stars. The purpose of this = observations is to help estimate the Hubble constant with an accuracy of = 10%. The observations were executed as scheduled, and no anomalies were = noted. 1.6 Completed WF/PC-2 5949 (High Resolution Imaging of Galaxies = Responsible for QSO Lyman Alpha Absorption.) The WF/PC-2 was used to make high resolution observations of Field = 0853 in order to study galaxies which are responsible for intermediate = redshift QSO Lyman Alpha absorption. It is the extended gaseous region = around these galaxies that produces the absorption. 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 = stars GRW+70D582 and G191-B2B in order to calibrate the photometric zero = point. The calibration was done for 18 WF/PC filters. The observations = were executed as planned, and no problems were reported. 1.8 Completed GHRS/1 6170 (GHRS Echelle and G140M Long-Term = Monitor-Cycle) The High Resolution Spectrograph (Side One) was used to make = calibration observations of standard star Mu-Col as part of a long term = monitoring of the Echelle spectrograph and grating G140M. The sensitivity = of the instrument will be measured at several grating positions. 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 : 8 Successful : 8 2.2 FHST Updates: Scheduled : 19 Successful : 19 2.3 Operations Notes: Real-time Operations moved back to the MOR from SAMS at 039/01:45Z = after completion of the SM-2 Internal Simulation #1. The simulation was = terminated two hours early due to adverse weather conditions. Up to that = point all simulation objectives were met. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH
