Shift L1959. Start at 336:13:00 GMT = 08:00am 01 Dec EST End 10:00am 01 Dec SOT Lead DAS (Times will be given in GMT on day 336.) PLAN ---- Continue running load NOV2904B. Finish obsid 6150, the ACIS-S/HETG study of pre-eclipse dips in HER X-1. Then obsid 4939, an ACIS-S observation of the gravitationally lensed system B1422+231. Obsid 5407, an ACIS-I observation of the X-ray luminous, young stars in the double cluster h and Chi Per will finish this orbit. No Comm this shift.

EPH temp 92.71 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three 34m contacts in the past day, no issues. One load segment uplinked, on-board loads good until 340:13:19. DEC0604 products being worked to try to get the same roll angle for two pieces of an observation that had to be split. Hopefully out today for a review at a time to be announced. DNS server problems were fixed by replacing memory and CPU. Look ahead: Draper will be working on electrical bus at back of building, will need to arrange a time in the next couple of weeks when power can be brought down.
