Shift L2121. Start at 132:13:00 GMT = 08:00am 12 May EDT End 11:00am 12 May SOT Lead DAS (Times will be given in GMT on day 132.) PLAN ---- Continue running load MAY1005A. Continue 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. Next Comms: 132:1350 to 1450 132:1845 to 1945 -- cancelled, transmitter problems 133:0050 to 0250 133:0430 to 0530 133:1500 to 1600 133:2245 to 2345 134:0345 to 0445 134:0855 to 1000 134:1145 to 1245 Orbital events: 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, 132:03:42, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 270.985 deg Dec = -24.373 deg ROLL = 89.206 deg Format = 2 OBSID = 5398 9 Sgr SIM FA = -467 SIM TSC = 75623 (ACIS-S) DITHER = ENAB HETG = IN ( 5.96 deg) LETG = OUT (77.59 deg) HRC-S HV is ON EPHIN Geom = LARG E150 = 15.4 E300 = 0.3 E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.6 LT 300. Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.9480 mu-a Ascending through 126591 km. ACIS focal plane temperature -119.5 degC. EPH temp 88.40 degF 13:59 AOS Status is essentially unchanged. Decending through 117074 km. ACIS focal plane temperature -119.5 degC. EPH temp 85.17 degF 14:52 LOS Decending through 115310 km. ACIS focal plane temperature -119.5 degC. EPH temp 85.17 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports in the past day, no issues. DSS-34, Canberra, is having transmitter problems, so our pass scheduled for 132:1745 callup is cancelled. No other station was available as a replacement. MAY1305A products have been generated to replan for a quick ToO. Incorporates the MAY1605 week, and provides for an ACIS focal plane cooling test during the HRC/LETG ToO observation. Review today at 1pm, on 405 244 5060 1165# NOTE CHANGE from pin 1159# given in an earlier email. To be followed by review of CAP 961 for replacement of loads. ToO will replace obsid's 6105, 5605, 5617, and 5818, which will all be rescheduled. A very short duration power spike was seen on transmitter B. These have been seen before and are not a concern. Solar proton fluxes have leveled off at about 300. There was a full halo CME late on Tuesday, probably associated with the M1.1 flare mentioned yesterday. We see a small electron shock at 131:0800 and an electron and MeV proton rise at 131:2000. Expect soft protons to follow. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- GOT and CXC/dataops very efficiently performed Rapid Processing on the GRB ToO. Results to observer and cdo as of last Midnight. ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
