Got no good dump data. Had to reschedule another support to avoid switchover to SSR-B. Did this (at 208:0200 approx, just prior to DSS-24 support scheduled for 0355) and got enough data to avoid switchover. - No CAPS Mission Planning (Ken): - Working on JUL3000 load. Products are out (as of 10:00am EDT and a load review will be held at 2:00pm. - Kevin working AUG06 load which includes the LETG insert/retract and more comet observations. Spacecraft Engineering (Jeff): - All is OK with S/C. - Wallace ran on-orbit solar array off-point demo (nominal case) on ASVT yesterday. All was OK, just a few minor tweaks needed. - LETG insert/retract products will be run today, also science recovery from safe mode. - Bill Peterson's last day is today. SOT (Bill Podgorski): - Radiation levels very low now. - OTG telecon this afternoon at 3pm. - Rob reviewing ACA dark current cal products now. DSOPS(Joy): - Three quick looks (see below). GOT(Chris) - All is OK. 3) Quick Look data review(OK unless noted): OBSID Target Time Comment ----- ------ -------------- ------- 00655 TERZAN 5/ACIS-I 2000:206:06:03:00 Streak visible.
