Shift L2799. Start at 080:12:00 GMT = 08:00am 21 Mar EDT End 10:00am 21 Mar SOT Lead DAS (Times will be given in GMT on day 080.) PLAN ---- Continue running load Mar1907C. Perform ascending CTI measurements, then obsid 8542, 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 8272, an ACIS-I observation of S0405 as part of a flux limited sample to study ICM temperature, mass, and substructure in low redshift clusters of galaxies.

One stored command segment uplinked, on-board loads good until 084:22:42. MAR2607B products released yesterday, load review at 2pm today. ACE solar protons remain at background level, and the sun is very quiet. A coronal hole is earth facing over the next few days.
