Shift L1702. Start at 079:13:00 GMT = 08:00am 19 Mar EST End 11:00am 19 Mar SOT Lead DAS (Times will be given in GMT on day 079.) PLAN ---- Continue running load MAR1904B (TOO replacement load). Finish obsid 4732, an ACIS-S observation of the near-by face-on spiral galaxy M101. This is part of a very long, 1 Ms, project. Then do the TOO observation 4587, an ACIS-S/HETG observation of the microquasar GRS 1915+105 during a correlated radio/X-ray flare. Next Comms: 079:1910 to 2010 080:0345 to 0445 080:1145 to 1245 080:1800 to 1900 081:0345 to 0445 081:0920 to 1120 081:1840 to 2040 082:0345 to 0445 082:1300 to 1500 082:2130 to 2330 Orbital events: 2004:079:01:12:14.691 637 EPERIGEE ORBIT PERIGEE 2004:080:08:56:39.017 638 EAPOGEE ORBIT APOGEE 2004:081:16:39:50.885 638 EPERIGEE ORBIT PERIGEE 2004:083:00:24:22.971 639 EAPOGEE ORBIT APOGEE 2004:084:08:08:15.032 639 EPERIGEE ORBIT PERIGEE 2004:085:15:52:26.401 640 EAPOGEE ORBIT APOGEE 2004:086:23:36:51.094 640 EPERIGEE ORBIT PERIGEE 2004:088:07:20:33.584 641 EAPOGEE ORBIT APOGEE 2004:089:15:05:04.243 641 EPERIGEE ORBIT PERIGEE EVENTS ------ Status at LOS, 079:11:59, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 210.791 deg Dec = 54.372 deg ROLL = 141.010 deg Format = 2 OBSID = 4732 M101 SIM FA = -467 SIM TSC = 75623 (ACIS-S) DITHER = ENAB HETG = OUT (79.46 deg) LETG = OUT (77.59 deg) HRC-S HV is ON EPHIN Geom = LARG E150 = 0.6 E300 = 0.0 E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.0 LT 300.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the last day. Two SCS uplinked, starting the TOO replacement load. On-board loads good until 81:09:22 VCDU will roll-over at approximately 080:2000. Problems from the MAR2204A load have been fixed, products expected out this morning for an email-only review today. Swapping the hardware CPE units appear to fix the problems which confounded the safe mode recovery simulation last week. The sim will be repeated next Tuesday. On Mar 21 the OCC network will be down at 1am EST for about 1 hour. Connectivity to the outside will be interrupted, but it will not affect internal data flow. MUPS tagup telecon today, 1pm EST, 405-244-5060, pin 1159#.
