Shift L2575. Start at 221:12:00 GMT = 08:00am 09 Aug EDT End 10:00am 09 Jul SOT Lead DAS (Times will be given in GMT on day 221.) PLAN ---- Continue running load AUG0706B. This entire orbit is obsid 6647, an ACIS-S/HETG observation of the bursting neutron star GS 1826-238, to obtain high quality spectra and search for absorption lines to measure the neutron star gravity.

EPH temp: 92.71 degF EPH 27V: 19.28 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day, no DSN issues. OC error turned off playback with 1:55 of SSR data left. Subsequent pass recovered about half the data, the remainder is expected to be recovered without an SSR roll-over. One stored command sequence was loaded; on-board loads are good until 224:15:35. CAP 425F was run to perform the routine EIA sequencer self-test. Test was successful. AUG0706A products were reviewed yesterday. AUG0706B were issued for email review by 2pm today. Soft solar protons are decaying slowly from the very small coronal stream event last Monday. Sun is expected to remain very quiet.
