Couldn't get good dump. real-time data was bad as well. - CAP 589 executed Sat evening to patch K constants to values for short eclipse. - Uplinked 3 load segments, good now thru 91:0740 - Two DSS-24 playbacks had missing VCDU's (lost forever), one had 530 missing, the other had 430. Details to be made available on http://icxc.harvard.edu/dsop/Dump_Sum.htm - Now scheduleing 1 hr. supports on 34m sites, more on 26m. Mission Planning (Dan Shropshire): - APR01A load review to be scheduled tomorrow or day after. - APR09 OR list available, being worked. - Need SI support for load reviews. Yousaf Butt for ACIS and Mike Juda/Jon Chappell/Gerry Austin for HRC. Eric Martin to fill in for Tom/Rob. Spacecraft Engineering(wallace Jackson/Jeff Shirer): - Andy Northrup working recovery procedure from safe mode. (turn CAPs into procedure). - Had bad data for trending on days 84 and 85. SOT (Bill Podgorski): - Radiation levels up over weekend but coming down, never got near alert level. - Discussed ACIS FP temp rise above -120 setpoint. - Discussed pegreta GRETA workstation diagnostics last week. ASCDSOPS(Joy Nichols): - 9 quick looks available (see below) 4) Quick Look data review: OBSID Target Time Comment ----- ------ -------------- ------- 00071 PG1634+706 2000:084:04:20 ACIS-S Cal Observation, looks OK 00070 PG1634+706 2000:084:02:35 ACIS-S Cal observation, looks OK. 00069 PG1634+706 2000:084:00:50 ACIS-S Cal observation, looks OK. 00047 PG1634+706 2000:083:20:57 ACIS-S Cal observation, looks OK. 00062 PG1634+706 2000:083:23:05 ACIS-S Cal observation, looks OK. 00611 W3B 2000:083:11:48 ACIS-I, looks OK 00859 NGC 4051 2000:084:05:56 ACIS-S/HETG, looks ok, can see lines. 00872 NGC 6503 2000:083:07:38 ACIS-S, all 5 chips are bright. 00539 Z5247 2000:083:17:26 ACIS-I, all 5 chips are bright.
