Shift L3506. Start at 056:13:00 GMT = 08:00am 25 Feb EST End 10:00am 25 Feb SOT Lead DAS (Times will be given in GMT on day 056.) PLAN ---- Continue running load FEB2309C. Finish obsid 10871, an ACIS-S ToO observation of the persistent neutron-star low-mass X-ray binary EXO 0748-676, to hopefully study cooling of the crust and thereby the crust structure. Then do obsid 10681, an ACIS-I GTO observation of the ultracompact HII (UCHII) region, G29.96-0.02 to study the interaction of the massive star wind with the surrounding molecular cloud. Then do obsid 10297, an ACIS-S observation of the AGN J1222+3602 to search for metal poor AGN in dwarf galaxies. Then do obsid 10684, an HRC-I GTO observation of M31 to monitor variability of the core sources, especially the super-soft X-ray sources. Then do obsid 10502, an ACIS-S observation of AX J194310+2318 to identify sources discovered in the ASCA galactic plane survey.

ACIS focal plane temperature -119.9 degC. EPH temp: 102.38 degF NOTES/ISSUES/PROBLEMS SOT lead station in TST room is not available due to water leak. No apparent damage to SOT lead or ACA equipment. From the 9am status meeting: Three supports over the past day, no issues. MAR0209A products were reviewed yesterday. MAR0209B released this morning for an email review by 2pm today. Yesterday there were two water leaks into the TST room. Equipment was safed per email from Chris Eagan yesterday. Plan is for Draper/JLL to repair the plumbing today, followed by a telecon to decide whether to remove the plastic coverings over the racks to begin damage assessment. ASVT and HRC GSE are the primary concerns. Power is off to ASVT, and an electrician should check the primary supply before restoring power and beginning unit by unit checkout of ASVT. At present, ASVT is NOT available for anomaly support, which Sabina identifies as the top priority. Second, the HRC anti-co patch verification is now on hold.
