Shift L3308. Start at 224:12:00 GMT = 08:00am 11 Aug EDT End 10:00am 11 Aug SOT Lead DAS (Times will be given in GMT on day 224.) PLAN ---- Continue running load AUG0811A. Finish obsid 9133, an ACIS-S observation of the globular cluster M28 to measure the position and magnetic field of a millisecond pular and constrain the neutron star equation of state. Then do obsid 9410, an ACIS-I observation of the cluster of galaxies RXCJ0105.5-2439, to study the X-ray vs. the gravitational lensing method of estimating cluster mass.

Has been re-started this morning. Status at LOS, 224:12:57, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 276.124 deg Dec = -24.870 deg ROLL = 274.141 deg Format = 2 OBSID = 9133 M28 SIM FA = -467 SIM TSC = 75624 (ACIS-S) DITHER = ENAB HETG = OUT (79.09 deg) LETG = OUT (77.21 deg) HRC-S HV is ON EPHIN Geom = SMAL E150 = 62.5 E300 = 5.1 E1300 = 5.8 LT 20.0 (RADMON P4GM = 0.0 LT 300. Triggers) P41GM = 0.0 LT 8.47 Descending through 136428 km. ACIS focal plane temperature -119.7 degC. EPH temp: 112.31 degF EPH 27V: 26.84 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Nine supports over the weekend. No issues. Three stored command segments uplinked, on-board loads are good until 228:03:44. AUG1808 products will be out this morning for review today. Coronal stream hit the Earth last Saturday, elevating the soft solar protons a factor of about 50, and decaying since then. This is still well below levels of concern to ACIS.
