Shift L818. Start at 290:12:00 GMT = 08:00am 17 Oct EDT End 11:00am 17 Oct SOT Lead DAS (Times will be given in GMT on day 290.) PLAN ---- Continue running load OCT1501B. Complete OBSID 1972, ACIS-S observation of the bright, radio loud Type IIn supernovae SN 1998S. Then perform CTI measurements surrounding perigee passage.

ACIS focal plane temperature remains -119.9. NOTES/ISSUES/PROBLEMS From the 9am status meeting: All dumps are current. Ran CAP 563A to check the CPE warm start count, which is still at 1 as expected. OCT2201B loads were finalized yesterday, need Flight Director signature. ASVT testing of the momentum envelope patches had problems with ASVT yesterday. Plan to continue today. Want to run a memory dump today -- need to have a CAP review. There is a problem getting a file from the DDTS system to support this. Offline-1 RAID failure was fixed yesterday, it is back up. Solar proton activity remains very low. There are warnings from the Solar Terrestrial Activity Report: "60-100% probability of M and X class flares. Another and much more intense region is rotating into view at the southeast limb today, this region could be capable of major flaring."
