Shift L2120. Start at 131:13:00 GMT = 08:00am 11 May EDT End 10:00am 11 May SOT Lead DAS (Times will be given in GMT on day 131.) PLAN ---- Continue running load MAY1005A. Finish obsid 5588, an ACIS-S ToO observation of a short duration gamma ray burst located by SWIFT. Then do obsid 5398, an ACIS-S/HETG observation to study emission lines in 9 Sgr, as part of a detailed survey of six normal O-type stars. This observation was shortened by the ToO, the remaining time will be scheduled when possible. Next Comms: 131:1200 to 1300 131:1900 to 2100 132:0245 to 0345 -- new contact, DSN changed schedule to support other mission 132:1350 to 1450 132:1845 to 1945 133:0430 to 0530 133:1500 to 1600 Orbital events: 2005:130:20:09:12.015 795 EPERIGEE ORBIT PERIGEE 2005:132:03:52:32.414 796 EAPOGEE ORBIT APOGEE 2005:133:11:37:03.027 796 EPERIGEE ORBIT PERIGEE 2005:134:19:20:34.872 797 EAPOGEE ORBIT APOGEE 2005:136:03:04:37.444 797 EPERIGEE ORBIT PERIGEE 2005:137:10:48:28.668 798 EAPOGEE ORBIT APOGEE 2005:138:18:32:11.566 798 EPERIGEE ORBIT PERIGEE EVENTS ------ Status at LOS, 131:12:58, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 189.057 deg Dec = 29.002 deg ROLL = 223.694 deg Format = 2 OBSID = 5588 GRB ToO SIM FA = -467 SIM TSC = 975623 (ACIS-S) DITHER = ENAB HETG = OUT (79.09 deg) LETG = OUT (77.59 deg) HRC-S HV is ON EPHIN Geom = LARG E150 = 11.0 E300 = 0.2 E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.0 LT 300.

EPH temp 89.48 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day, no issues. Ran CAP 959 to replace the MAY0905B load with MAY1005A to accomodate the gamma ray burst ToO. On-board loads are good until 135:03:45. Products for MAY1605 are out for review at 2pm today. Solar proton fluxes continue to decrease slowly. Several C-class flares and one M-class in the past day. Low probability of a CME impact. Star selection and aspect working group meeting cancelled today. All-hands meeting at 3pm today in the first floor conference room. Roger and Chris will discuss Draper construction and Linux Migration.
