Shift L1698. Start at 075:13:00 GMT = 08:00am 15 Mar EST End 10:00am 15 Mar SOT Lead DAS (Times will be given in GMT on day 075.) PLAN ---- Continue running load MAR1504B. Running obsid 4497, ACIS-I observation of the young stellar object L1448 N-A, looking for shock-heated plasma from protostellar jets. Then do three calibration observations of CAS A.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: Eight supports over the weekend. No issues. Two segments of MAR1504B were uplinked, on-board loads good until 079:05:34. Ran a momentum dump (CAP 830A) on Saturday, performance was nominal. Dump lasted 10s longer than predicted, but this is within the prediction uncertainty. MAR2204 products out late today or early tomorrow for a load review tomorrow. Safemode SIM planned for all day tomorrow. Will be used for training, and for re-baselining the ASVT following changes for installation at the OCC. March ephemeris load has been signed off, needs a CAP review. Greg Wright to be visiting Tues-Fri to discuss migration to LINUX.
