To:sot_shift from: Dan Schwartz date: 21 Nov 03, 12:00noon EST Subject: SOT shift report 2003-11-21 L1583 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/ascwww/AXAF/extra/science/htdocs/acis/SOT_reports/Nov_21_2003_L1583.txt. Shift L1583. Start at 325:13:00 GMT = 08:00am 21 Nov EST End 12:00 noon 21 Nov SOT Lead DAS (Times will be given in GMT on day 325.) PLAN ---- Continue running load NOV1703B. Finish obsid 4007 and then do obsid 4008. These are both ACIS-S observations, searching for a low level of activity from the supermassive black hole in the nuclei of the elliptical galaxies NGC 4486B and NGC 4564, respectively.

ACIS focal plane temperature -119.9. 14:55 Playback completed. 15:58 LOS Status is essentially unchanged. Ascending through 100401 km. ACIS focal plane temperature -119.9. NOTES/ISSUES/PROBLEMS Solar proton fluxes remain quite high at ~20,000. We can operate for one day at such rates, accumulating a fluence of 1.7E9. There was another frontside CME yesterday, with a plane-of-sky speed 547 km/s. We may expect more particle activity forthcoming, and in the next ten days while the active regions from last month remain on the front of the sun. From the 9am status meeting: Two supports in the past day. No issues. On-board loads good until 327:10:56. DEC0103 products are expected to be ready early next week. Target is to sign-off by Wednesday, due to the Thanksgiving holiday. Next Monday, Nov 24, the network link to the OCC will be down from 10am - noon, for installation of a faster link. This time is scheduled between ground supports. Note that Monday morning's SOT shift report will be delayed until after the network connection is restored in the afternoon.
