Shift L2801. Start at 082:12:00 GMT = 08:00am 23 Mar EDT End 10:00am 23 Mar SOT Lead DAS (Times will be given in GMT on day 082.) PLAN ---- Continue running load MAR1907C. Finish obsid 7797, an ACIS-I observation of Centaurus A to study the jet, knots, interactions at the radio lobe, and properties of the binary X-ray sources. Then do obsid 7709, an ACIS-I GTO observation of MS1455.0+2232 as part of an exploratory survey for X-ray outbursts in rich clusters of galaxies. Then obsid 7454, an ACIS-S observation of the AM CVn type double degenerate binary SDSS J1208+3550, as part of a survey of such systems. Then perform cti measurements surrounding perigee passage.

One stored command segment uplinked, on-board loads good until 086:12:30. Offline system issues with the APR0207 products have cleared, and products may be out for review on Monday. ACE solar protons remain at background level, and solar activity is minimal. A coronal hole is earth facing over the next few days.
