HUBBLE SPACE TELESCOPE DAILY REPORT #2199 PERIOD COVERED: 0000Z (UTC) 08/31/98 - 0000Z (UTC) 09/01/98 Daily Status Report as of 244/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed NIC/1/2/3 7898 (Snapshot Survey of Proto-planetary Nebulae) The Near Infrared Camera (Cameras One, Two and Three) was used to make snapshot survey observations of the protoplanetary nebula IRAS18184. This is to help discern the structure of the nebulae and the evolutionary sequence that produces axially symmetric planetary nebulae. The observations were executed as scheduled, and no anomalies were noted. 1.2 Completed Three Sets of WF/PC-2 7712 (WF/PC-2 Cycle 7 Supplemental Darks pt2/3) The WF/PC-2 was used to make a series of Cycle 7 supplemental calibration darks. This dark calibration program obtains three dark frames every day to provide data for monitoring and characterizing the evolution of hot pixels. The observations were executed as scheduled, and no anomalies were noted. 1.3 Completed Two 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. The observations were executed as scheduled, and no anomalies were noted. 1.4 Completed NIC/1/2 7877 (Infrared Luminous Stars & Stellar Population in Nearby Giant Elliptical Galaxies) The Near Infrared Camera (Camera One and Two) was used to make observations of infrared luminous stars in the nearby giant elliptical galaxy NGC-5128. These data will yield the first infrared luminosity functions for the stellar populations of giant ellipticals as well as unique optical/infrared color-magnitude diagrams for individually resolved stars. The observations were executed as scheduled, and no anomalies were noted. 1.5 Completed Six 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 take in parallel with the prime science observations. The observations were completed as planned, and no problems were reported. 1.6 Completed WF/PC-2 8061 (POMS Test Proposal: WF-II Backup Parallel Archive Proposal) This is a POMS test proposal designed to simulate scientific plans. The proposal was executed as planned, and no anomalies were reported. 1.7 Completed Two Sets of WF/PC-2 8059 (POMS Test Proposal: WF-2 Targeted Parallel Archive Proposal) The WF/PC-2 was used to make observations in parallel with the prime science observations. The parallel opportunities available with WF/PC-2 in the neighborhood of bright galaxies are treated in a slightly different way from the normal pure parallels. Local group galaxies offer the opportunity for a closer look at young stellar populations. The observations were completed as planned, and no anomalies were reported. 1.8 Completed STIS/CCD 8064 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal - Backup) The Space Telescope Imaging Spectrograph (CCD) was used to conduct a non-scripted parallel POMS test. The observations were completed as scheduled, and no problems were reported. 1.9 Completed Three Sets of WF/PC-2 7620 (WF/PC-2 Cycle 7 Standard Darks) The WF/PC-2 was used to make a series of Cycle 7 standard dark calibration images. This dark calibration program obtains dark frames every week in order to provide data for the ongoing calibration of the CCD dark current rate, and to monitor and characterize the evolution of hot pixels. The observations were executed as scheduled, and no anomalies were noted. 1.10 Completed NIC/1 7344 (Witnessing the Birth of Radio Galaxies: WF/PC-2 & NICMOS Observations of CSOs) The WF/PC-2 was used to make observational images of the cores of bright, nearby galaxy (Compact Symmetric Object) CSO 1943+70 in order to try to witness the birth of a radio galaxy. Only HST can image these galaxies at the same size scale of the CSO itself, also allowing us to search for nuclear structures aligned with the radio source in this formative stage. The observations were completed as planned, and no anomalies were reported. 1.11 Completed Two Sets of NIC/2/3 8063 (NICMOS Pure Parallel Sponge - Backup) The Near Infrared Camera (Cameras Two and Three) was used to make observations taken in parallel with the prime science observations. This proposal is PRE-the new FOM default. The observations were executed as scheduled, and no anomalies were noted. 1.12 Completed NIC/1/2/3 7837 (The Changeover From H to He Rich Mass Loss in PN) The Near Infrared Camera (Cameras One, Two and Three) was used to make observations of the bright planetary nebula BD+303639. This planetary nebula has helium rich stellar atmospheres and helium poor nebulae. The observations were executed as scheduled, and no anomalies were noted. 1.13 Completed NIC/1 7867 (NICMOS Imaging of the Dusty CfA Seyfert Nuclei) FGS 7968 () The Near Infrared Camera (Camera One) was used to make imaging observations of the dusty CfA class Seyfert galaxy NGC-7682. These data will allow us to determine if the Seyfert 1/2 dichotomy is best explained by the unified model, the evolutionary picture, or a combination of both of these scenarios. The observations were executed as scheduled, and no anomalies were noted. 1.14 Completed Two Sets of STIS/MA1/MA2 7604 (Cycle 7 MAMA Dark Measurements) The Space Telescope Imaging Spectrograph (MA1 and MA2) was used to make MAMA dark measurements. These darks will be used in later image reductions and also trended over the instrument's life time as an indicator of the detector's degradation or damage. The observations were completed as scheduled, and no problems were reported. 1.15 Completed NIC/1/2/3 7888 (Young and Intermediate Aged Clusters in M-33 as Stellar Laboratories) The Near Infrared Camera (Cameras One, Two and Three) was used to make observations of the cluster NGC-598 which is located within the nearby galaxy M-33. This cluster will be used as a stellar laboratory to study the bright asymptotic giant branch {AGB} stars expected in their fields. The observations were executed as scheduled, and no anomalies were noted. 1.16 Completed NIC/2 7835 (A Search for Superplanets Embedded in Beta Pic & Vega-like Circumstellar Disks) The Near Infrared Camera (Camera Two) was used to make observations of the circumstellar disk around star HD48682 in order to search for superplanets. The discovery of a circumstellar disk orbiting Beta Pictoris as well as the discovery of other similar IR-excess Vega-like systems have provided compelling evidence that our solar system, or at least many of the processes which are thought to have created it, may be far from unique. The observations were executed as scheduled, and no anomalies were noted. 1.17 Completed WF/PC-2 7909 (POMS Test Proposal: WF II Parallel Archive Proposal) The WF/PC-2 was used to make parallel observations as part of the POMS test proposal. This test proposal is designed to simulate scientific plans. The observations were completed as planned, and no problems were reported. 2.0 FLIGHT OPERATIONS SUMMARY: Guide Star Acquisitions: Scheduled Acquisitions : 9 Successful : 9 Scheduled Reacquisitions : 6 Successful : 6 2.2 FHST Updates: Scheduled : 14 Successful : 14 2.3 Operations Notes: No operational porblems were reported and no HSTARs were written.
