To:sot_shift from: Dan Schwartz date: 27 Dec 00, 12:00noon EST Subject: SOT shift report 2000-12-27 L524 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/ascwww/AXAF/extra/science/htdocs/acis/SOT_reports/Dec_27_2000_L524.txt. Shift L524. Start at 362:17:00 GMT This is a remote snapshot report. There is no planned on-site SOT coverage during Dec 23 -- Jan 1, inclusive. SOT Lead DAS (Times will be given in GMT on day 362. In general times are rough, not precise.) PLAN ---- Continue running load DEC2500c. Do an ACIS-S/HETG observation of the distant, massive cooling flow cluster Zw3146, OBSID 1651, for the entire orbit. Next Comms: (from planning schedule) 363:01:00 to 02:00 363:11:00 to 12:00 363:21:00 to 22:00 364:07:00 to 08:00 364:17:00 to 18:00 365:00:55 to 01:55 365:08:35 to 09:35 365:18:40 to 20:05 366:03:00 to 04:00 366:12:15 to 13:15 366:21:10 to 22:10 Orbital events: 2000:363:06:57:59.277 192 ORBIT PERIGEE 2000:364:14:41:20.624 193 ORBIT APOGEE 2000:365:22:26:03.214 193 ORBIT PERIGEE EVENTS ------ Status at LOS, 362:16:59, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 155.927 deg DEC = 4.180 deg ROLL = 65.650 deg Format = 2 OBSID = 1651 Zw 3146 SIM FA = -467 SIM TSC = 75623 (ACIS-S) HETG = IN ( 6.34 deg) LETG = OUT (78.34 deg) HRC-S HV is ON EPHIN Geom = LARG E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.0 LT 300.

NOTES/ISSUES/PROBLEMS ACE radiation still extremely low, flux about 50. In regard to the snapshot web page being blank, as reported yesterday, Rob Cameron replied: "The snapshot archive was resident in /pool7/snarc/. However, pool7 died overnight and will not be available for a day or two. I have re-directed the snapshot archive to /pool14/snarc, but now the archive is only one frame deep, because of the loss of history. http://asc.harvard.edu/%7erac/snap/snap.cgi now points to the new archive. I have temporarily made a replacement for Tom's snapshot browser: http://asc.harvard.edu/~rac/snaps.cgi - Rob" Scott reports: "We have been developing a new snapshot. I have put this on line as it doesn't use pool disks. Also there is always a hot backup to the snapshot available by going to the SOT Mirror site. These both use different pathways than Rob's snapshot" Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 2313 CDFS 356:02:28 ACIS-I Off-axis picture, does not show sources. 1848 3C 58 358:07:47 HRC-S extended source 2239 CDFS 358:17:49 ACIS-I Some sources visible ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 800-759-8352 PIN 1636502 or e-mail 1636502@skytel.com -------------------------------------------------------
