HUBBLE SPACE TELESCOPE DAILY REPORT #1113 PERIOD COVERED: 0700 EST Daily Status Report as of 098/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed Two Sets of WF/PC-2 5561 (WF/PC-2 Cycle 4 Calibration: Internal Monitor. 2: Flats) The WF/PC-2 was used to make a visual flat calibration images to monitor flat field stability as well as the stability of the analog-to-digital converters. The observations were monitored by the OSS, and no anomalies were noted. The data has not yet been analyzed due to problems with ground receipt. A LOR from WSGT is expected. 1.2 Completed WF/PC-2 5404 (Narrow-Band Imaging fo Hydrogen-Poor Planetary Nebulae Cycle 4 High) The WF/PC-2 was used to make narrow band images of the small dynamical structure of the hydrogen-poor planetary nebula IRAS1833-2. This nebula contains gas that consists of nearly undiluted products of the nuclear burning that is thought to result when a final helium shell flash occurs after the complete removal of the hydrogen envelope. Four images were received and displayed. No anomalies were noted. 1.3 Completed WF/PC-2 5475 (A Snapshot Survey for Blue Stragglers in Magellanic Cluster Cores) The WF/PC-2 was used to make short exposure snapshot images of the blue straggler stars located in populous cluster NGC-339. A populous cluster is the Magellanic Cloud equivalent of a galactic globular cluster. The observations were made with two different color filters. The intent is to find out if blue straggler stars exist within these clusters. Both of the images were received and displayed. They were reported to look nominal. 1.4 Completed WF/PC-2 5415 (The Distance to the M-96 Galaxy Cluster: Cycle 4 Medium) The WF/PC-2 was used to make observations of Cepheid variable stars within the galaxy NGC-3368 which itself is located in the M-96 galaxy cluster. This is to help determine the distance to this galactic group, and to improve the determination of the Hubble constant. The observations were received and displayed. No anomalies were noted, although full analysis is pending receipt of the STR dump. 1.5 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earthflats, Large Set) The WF/PC-2 was used to make a set of Earth flat calibration images using different filters in order to construct high quality flat fields of the OTA illumination pattern. The OSS monitored the observations and assessed the data quality. No anomalies were noted. Of the 8 exposures, 4 were underexposed and 1 was saturated. 1.6 Completed GHRS/2 5358 (The Chromosphere of Alpha Tau: Cycle 4 Medium) The High Resolution Spectrograph (Side Two) was used to make spectroscopic observations of the chromosphere of the star Alpha Tauri. The baseline guidestar acquisition failed to make fine lock. The observations continued in coarse track. The onboard target acquisition probably succeeded. No problems were noted. All data remains on the STR. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 4 Successful : 3 (failure at 097/2213Z; FGS#3 failed to acq; remained in coarse track) Scheduled Reacquisitions : 9 Successful : 9 2.2 FHST Updates: Scheduled :11 Successful :11 2.3 Significant HSTARs: None 2.4 Operations Notes: There were no significant reported problems in any HST subsystem. 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete Three Sets of WF/PC-2 5475 (A Snapshot Survey for Blue Stragglers in Magellanic Cluster Cores) 3.2 Complete Two Sets of WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: Internal Monitor 3: Darks) 3.3 Complete FGS 5333 (Linking the HIPPARCOS to the Extragalactic Reference Frame, BR12-23, Part 2) 3.4 Complete WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 High Galactic Latitude) 3.5 Complete WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal Monitor. 1) 3.6 Complete WF/PC-2 5397 (Determination of the Extragalactic Distance Scale.
