SOT shift report 2000-10-17 L453 Start at 2000:291:12:08 GMT = 2000 Oct. 17 08:08am EDT End 11:45am EDT See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/ascwww/AXAF/extra/science/htdocs/acis/SOT_reports/Oct_17_2000_L453.txt SOT Lead Ed Kellogg Plan: ---- Doing OBSID 61879 Cal-ERs, then OBSID 01872, NGC 2068 2000:292:05:35 95.0 ksec, ACIS-I NONE, SEARCH FOR X-RAYS FROM COLLAPSING MAGNETIZED PRE-STELLAR CONDENSATIONS At the 9 am meeting we decided to stop SSR-A and record on B so we can re-dump A to recover the data lost earlier this AM at JPL. SSR-B will be used for some day(s) until we can do a patch to dump A. EVENTS GMT OBSID -------------- ---- ----- AOS, 0 fids, 8 stars 1552 61879 Execute CAP 664 SSR Record transition A->B 1555 Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day SSR dumps 4 Data loss big chunk lost from this AM 0200 playback(see below) Load is good -> 294:07:30 CAPs - next passes 1545, 0000, 0935 MP: Oct2300 products out Oct3000 has no OR list, due yesterday. Ken will call SOT MP. S/C: Tests on star field dropped last May succeeded in 5 of 6 cases. The wider magnitude limit was the key. A mod will be proposed to get more candidate stars + use the wider magnitude limit, which was shrunk down last May. The one remaining case is under further investigation. We discussed trying to recover the lost data from this AM by switching to SSR-B and resetting the pointers on SSR-A to play back the data again. This requires a patch. A meeting is set to discuss this further. GOT: - SOT: Radiation moderately low and stable. Requested info on significance of XWin1 servicing. This is the workstation in the ACIS room, which is scheduled for a HDD replacement some time this week. Email was sent to Butt, Plucinsky & Bautz to see if it will impact them. ASCDS: Several quicklook results. Also they're trying to process the data with gaps from this AM. OCC Mgr: There is a meeting at 3:30 today at OCC with the MSFC Director, Art Stephenson, including recognition awards. All are invited!!
