- HUBBLE SPACE TELESCOPE
- DAILY REPORT #788
-
- PERIOD COVERED: 0800 EST 12/18/92 - 0800 EST 12/21/92
-
- Daily Status Report as of 356/1200Z.
-
- 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
-
- 1.1 Completed Six Sets of GHRS/2 3482 (Nature and In-Falling of Matter
- on Star Beta Pictoris)
-
- The High Resolution Spectrograph was used to make ultraviolet
- observations of the gaseous disk around star Beta Pictouis (aka,
- HD39060) looking for cometary like objects which might be falling in
- to the disk and evaporating on contact. A total of 24 spectra were
- received and displayed. They were reported to be okay. Two
- observations did not occur because of GHRS carousel reset problems.
-
- 1.2 Uplinked Updated Ephemeris Tables, Per MOSES 2871
-
- Uplinked at 354/0102Z and 356/0057Z.
-
- 1.3 Completed PC 4093 (Survey of Nuclear Regions of Markarian Galaxies)
-
- The Planetary Camera was used to take two images of two separate
- Markarian galaxies (MARK 382 and NGC-985) looking in their inner
- core regions and using filter F785LP. Both images were received and
- displayed in the OSS. Both images were reported to look okay.
-
- 1.4 Completed WFC/PC 4109 (WF/PC Calibration:Rapid Internal Monitor)
-
- Both the Planetary Camera and the Wide Field Camera were used to
- take internal flat observations which are checking for different
- forms of contamination (i.e., daisies and measles). The OSS
- monitored the observations and assessed the quality of the data. No
- problems were reported.
-
- 1.5 Completed Two Sets of GHRS/2 4068 (GHRS Detector Calibrations)
-
- The High Resolution Spectrograph was used to make internal flat
- calibration observations to check on the stability of the detectors.
- The observations were received and displayed. No problems were
- reported.
-
- 1.6 Completed PC 4140 (WF/PC Calibration: Rapid Internal Monitor Part 2)
-
- The Planetary Camera was used to make two internal flat observations
- checking on new forms of contamination, and the reappearance of
- quantum efficiency hysteresis. Both images were received and
- displayed. They both were reported to look okay.
-
- 1.7 Completed PC 4163 (Evolution of Solar Nebulae Surrounding Pre-Main
- Sequence)
-
- The Planetary camera was used to make internal Earth flat
- calibration images to be used later to process images of nebulae
- around pre-main sequence stars. Five images were received and
- displayed. Three images were reported to be saturated, one was
- underexposed, and one was reported to be okay.
-
- 1.8 Completed GHRS/2 4065 (Dark Noise Monitoring HRS)
-
- The High Resolution spectrograph was used to make internal dark
- observations to check on the levels of detector dark noise. The
- observations were executed as scheduled, and no problems were
- reported.
-
- 1.9 Completed PC 3551 (Elliptical Galaxies with Kinematically Distinct
- Nuclei)
-
- The Planetary Camera was used to take two image of elliptical galaxy
- NGC-4494 looking at the stellar component of its nucleus. It is
- known to be kinematically distinct from the stars in the rest of the
- galaxy. Both observations were received and displayed. Both were
- reported to look okay.
-
- 1.10 Completed FOC/96 4096 (Far Ultraviolet Spectra of High redshift
- Quasars)
-
- The Faint Object Camera (f/96) was used to obtain three ultraviolet
- objective prism images of high red shift quasar Q1451+124. All three
- images were received and displayed. It was noted that they all had a
- background level of around 7-10 counts, which is higher than usual.
-
- 1.11 Completed FOS/BL 3816 (White Dwarf Stars)
-
- The Faint Object Spectrograph was used to obtain spectral
- observations of white dwarf stars. Three observations were received
- and displayed. The first observations was a binary target
- acquisition, and had ten groups. The following two observations were
- reported to look okay. Shortly after the FOS came up to its final
- high voltage, a status buffer error message was received. It appears
- to be caused by a GIMP test. An HSTAR was written.
-
- 1.12 Completed WFC 4105 (HST Medium Deep Survey,High Latitude)
-
- The Wide Field Camera was used to take an image to be used for a
- high latitude survey. This image was taken in parallel with the
- prime science observations. It was received and displayed in the
- OSS. It was reported to look okay.
-
- 1.13 Completed WFC 4713 (Internal Delta Flats)
-
- The Wide Field Camera was used to make position measurements of the
- star Proxima Centauri to determine the presence of a Jupiter sized
- planet in orbit around the star. The observations were complete as
- scheduled, and no problems were reported.
-
- 1.14 Completed GHRS/2 2851 (Pulse Height Analysis (PHA))
-
- The High Resolution Spectrograph was used to make internal flat
- observations which will be used for the restoration of Earth flat
- images. These were altered due to changes in the quantum efficiency
- which occurred after WFPC decontamination operations. The
- observations were monitored in the OSS. No problems were reported.

- There will be a partial eclipse of the Sun at the end of Dec. 23 and
- the start of Dec. 24. This will effect two orbital passes of the
- Space Telescope, one orbit in each day. The First orbit will be
- effected for a 20 minute period, with a maximum of 37% reduction in
- Sun light. The second orbit will be effected for six minutes, with a
- 2.4% reduction in Sun light. The Battery Rate of Charge Test will be
- disabled in the EPS System, and the Course Sun Sensors in the PCS
- System.
-
-
- Due to the Christmas and New Years holidays no daily reports will be
- written on Thursday Dec. 24, Friday Dec. 25, and Friday Jan. 1. A
- daily report will be written Monday Through Thursday (Dec. 28 - Dec.
- 31).
