Shift L2798. Start at 079:12:00 GMT = 08:00am 20 Mar EDT End 10:00am 20 Mar SOT Lead DAS (Times will be given in GMT on day 079.) PLAN ---- Continue running load MAR1907C. Finish obsid 8268, an ACIS-I GTO observation of the low-redshift galaxy cluster A3528s, part of a flux limited sample to study ICM temperature, mass, and substructure. Then obsid 8539, an ACIS-S/HETG observation of SN 1987A to study lines between O VII and Fe-K, and construct spatial-velocity-ionization models in conjunction with LETG/ACIS data. Then obsid 7806, an ACIS-S observation of IRAS F09111-1007 as part of a complete sample of Luminous Infrared Galaxies, followed by cti measurements surrounding perigee passage.

EPH temp: 97.37 degF EPH 27V: 16.10 NOTES/ISSUES/PROBLEMS For quite some time EPHIN leakage currents have been reading either a saturated level or zero. I will no longer report these values. From the 9am status meeting: Three supports over the past day, no issues. One stored command segment was uplinked, on-board loads are good until 083:10:12. MAR2607A products were out yesterday, load review will be at 2pm today. ACE solar protons remain at background level, and the sun is very quiet.. A coronal hole will be earth facing over the next few days.
