Shift L2457. Start at 103:13:00 GMT = 08:00am 13 Apr EDT End 10:00am 13 Apr SOT Lead DAS (Times will be given in GMT on day 103.) PLAN ---- Continue running load APR1006B. Finish obsid 7320, continuing the ACIS-S/HETG observation of DX Cha in the epsilon Chamaeleontis Group to obtain a high-resolution spectrum of an Herbig Ae star. Then into the radiation belt passage.

EPH temp: 91.63 degF EPH 27V: 21.23 12:57 LOS Status is essentially unchanged. Descending through 110295 km. ACIS focal plane temperature -119.5 degC. EPH temp: 94.86 degF EPH 27V: 19.40 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the last 24 hours. No issues. One SCS segment was uplinked, on-board loads good until 106:15:27. Yesterday the APR1706B loads were approved. As part of the FSW recompile effort, CAP 750 will be run over the next few days to dump checksum memory. ACE 115-195 protons are around the 2200 level. Not a concern this orbit, since HETG is inserted and there are only about 40ks until perigee. Will keep watch upon egress tomorrow. Web acess and IVODS issues from yesterday were fixed. Meeting: A six sigma debrief meeting will be at 11:00 am in the conference room, on 1165#. This is intended as a repeat of Monday's debrief at 60 Garden st.
