HUBBLE SPACE TELESCOPE DAILY REPORT #2259 PERIOD COVERED: 0000Z (UTC) 11/25/98 - 0000Z (UTC) 11/30/98 Daily Status Report as of 334/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed Eleven Sets of WF/PC-2 7713 (WF/P-2 Cycle 7 Supplemental Darks pt3/3) The WF/PC-2 was used to make supplemental dark calibration images. This dark calibration program obtains three dark frames every day to provide data for monitoring and characterizing the evolution of hot pixels. As described in 2.1 and HSTAR 6789, the acquisition and/or re-acquisitions for the fifth and sixth iterations of this proposal defaulted to fine lock backup on one FGS only. Otherwise, the observations were completed as planned, and no further anomalies were noted. 1.2 Completed Fifty-Three Sets of NIC/1/2/3 7963 (Darks: Warming Up) The Near Infrared Camera (Cameras One, Two and Three) was used to monitor the detector dark current during the interval between the end of science observations and the exhaustion of cryogen and subsequent warming of the dewar to > 100K. As described in 2.1 and HSTAR 6789, the acquisition and/or re-acquisitions for the 17th through the 21st iteration of this proposal defaulted to fine lock backup on one FGS only. Otherwise, the observations were completed as planned, and no further anomalies were noted. 1.3 Completed Seven Sets of STIS/CCD 7948 (CCD Dark and Bias Monitor -- Cont. to Dec. 98) The Space Telescope Imaging Spectrograph (CCD) was used to measure CCD dark current and bias rates for the two supported amplifier settings {GAIN=1 and GAIN=4} in order to gather data for making superdarks and superbiases. The data will be used to track the growth of hot pixels on the CCD in general and within the various target acquisition apertures specifically. As described in 2.1 and HSTAR 6789, the acquisition and/or re-acquisitions for the fourth iteration of this proposal defaulted to fine lock backup on one FGS only. Otherwise, the observations were executed as scheduled, and no further anomalies were noted. 1.4 Completed Seventeen Sets of NIC/1/2/3 7961 (Flats: Warming Up) The Near Infrared Camera (Cameras One, Two and Three) was used to monitor the flat fields during the interval between the end of science observations and the exhaustion of cryogen and subsequent warming of the dewar to > 100K. These flats will provide a monitor for particulate comtamination and detector lateral position {from the coronagraphic spot and FDA vignetting}. As described in 2.1 and HSTAR 6789, the acquisition and/or re-acquisitions for the eighth this proposal defaulted to fine lock backup on one FGS only. Otherwise, the proposal completed with no further reported problems. 1.5 Completed Six Sets of STIS/CCD 8084 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal Continuation) The Space Telescope Imaging Spectrograph (CCD) was used to make non-scripted parallel high galactic latitude observations as part of POMS test proposal.

The WF/PC-2 was used to make deep observations of the lensing double quasar system Q2345+007. The current evidence suggests that this double QSO results from the gravitational lensing effects of a large compact mass at z = 1.49. If so, this early formation of compact structure is not compatible with many forms of dark matter. The observations were executed as scheduled, and no anomalies were noted. 1.9 Completed Twenty-Four Sets of STIS/CCD 8062 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal Continuation) The Space Telescope Imaging Spectrograph (CCD) was used to make high galactic latitude observations taken in parallel with the prime science observations.

Because of the extreme youth of this object, any low-mass brown dwarf and planetary companions will still be in a higher luminosity phase and thus easily detectable. A dark calibration image was also taken. As described in HSTAR 6788 and 2.1, there was a loss of lock during the execution of this proposal. Otherwise, the observations were executed as scheduled, and no further anomalies were noted. 1.13 Completed STIS/CCD/MA2 7433 (UV Spectral Dating of Galaxies) The Space Telescope Imaging Spectrograph (MA2) was used to make ultraviolet spectrographic observations of HD70110 to calculate a highly accurate library of UV stellar spectra that can be used to estimate the age and metallicity of galaxies of intermediate age {between 1 and 8 Gyrs}. The critical step in this effort is to test the model spectra against high-quality UV spectra of real stars. A wave length calibration image was also taken.

A bias calibration and an internal flat calibration image were also taken. The observations were executed as scheduled, and no anomalies were noted. 1.16 Completed STIS/CCD 7310 (The Interaction of Accretion Disks with Protostellar Binaries) The Space Telescope Imaging Spectrograph (CCD) was used to study the interaction of the accretion disk with the protostellar binary system DF-Tau. This should determine how the accretion disk interacts with stars in young binary systems and will measure the rates that mass accumulates onto each component of the pair. The observations were executed as scheduled, and no anomalies were noted. 1.17 Completed WF/PC-2 6673 (Black Holes and Gas Disks in a Complete Sample of Radio Loud UGC Ellipticals) The WF/PC-2 was used to make observations of radio load, elliptical galaxy UGC-12531 in order to search for a possible black hole and gas disks.

The purpose the of observations is to obtain a set of emission-line diagnostics of the Orion Nebula in its brightest and best-resolved H II region. As described in 2.1 and HSTAR 6789, the acquisition and/or re-acquisitions for this proposal defaulted to fine lock backup on one FGS only. Otherwise, the observations were completed as scheduled, and no further anomalies were reported. 1.20 Completed Seven Sets of NIC/2/3 8082 (NICMOS Pure Parallel Fall 98) The Near Infrared Camera (Cameras Two and Three) was used to make pure parallel observations while another instrument is prime. As described in 2.1 and HSTAR 6789, the acquisition and/or re-acquisitions for the second, third and fourth iterations of this proposal defaulted to fine lock backup on one FGS only. Otherwise, the observations were executed as scheduled, and no further anomalies were noted. 1.21 Completed Two Sets of WF/PC-2 6745 (Fundamental Plane, Morphology-Density Relation, and Lensing in the z=0.58 Arc Cluster CL2053) The WF/PC-2 was used to make observations of the galactic cluster Gal-Clus-2053 in order to study its fundamental plane structure, its morphology-density relation, and its lensing.
