SOT shift report 2000-11-01 M468 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/ascwww/AXAF/extra/science/htdocs/acis/SOT_reports/Nov_01_2000_M468.txt. Shift M468. Start at 306:17:00 GMT = 12:00pm 01 Nov EST End 2:00pm 01 Nov SOT Lead Mark Freeman (Times will be given in GMT on day 306. In general times are rough, not precise.) PLAN ---- Continue running load OCT3000c. Continue ACIS-S observation OBSID 2052, a deep census of X-ray sources in M31, manuever to OBSID 794, a search for GALACTIC FOUNTAINS AND SUPERNOVAE in the normal spiral galaxy NGC 891, and then prepare instruments for perigee passage and do CTI measurement.

Unless a significant upturn is experienced in the next 15 hours or so, we should be OK on total fluence for this orbit. P4GM has dropped to about half of its earlier level. 3) Squirt Data: ACA EGSE is operating nominally with the new squirt software. It appears that the HRC EGSE is currently not processing telemetry, although I cannot tell if this is normal, or the result of another problem, or the squirt software. Left a message for Jon Chappell to let him know he should check it out.
