To:sot_shift from: Dan Schwartz date: 29 Mar 10, 10:00 EDT Subject: SOT shift report 2010-03-29 L3903 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/web-cxc/htdocs/acis/SOT_reports/Mar_29_2010_L3903.txt. Shift L3903. Start at 088:13:00 GMT = 08:00am 29 Mar EDT End 10:00am 29 Mar SOT Lead DAS (Times will be given in GMT on day 088.) PLAN ---- Continue running load MAR2910A. Finish obsid 12045, the Chandra Deep Field South, an ACIS-I series of observations to double the deepest exposure of any Chandra field. Then do obsid 12081, an ACIS-S DDT observation of the gravitationally lensed quasar Q0957+561AB in response to a discovery of optical variability in one of the images. Then do obsid 11802, a GTO HRC-S/LETG observation of the isolated white dwarf GD153, to constrain white dwarf parameters and calibrate low energy response of detectors. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Nine supports over the weekend, no issues. Two stored command sequences uplinked, on-board loads are good until 092:04:09 APR0510 products expected out Wednesday, possibly Tuesday. No spacecraft issues. Sun is quiet. Backup T1 line to JPL is down. Being diagnosed. ACIS has waived off the software upload for tomorrow because the length of comm is too short considering possible contingencies. ACIS TST4 has been replaced -- the monitor is jittering and that is being diagnosed.
