SOT shift report 2007-09-17 L2979 File created at 2007:260:12:21 UTC = 08:21 AM Sep-17-2007 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg SOT: The ACIS detector housing heater B side was turned off, and then back on again last night; the camera body temperature (1CB[A/B]T) cooled too much to leave it off, and cooled a bit faster than expected, but within the range of the model predictions. There will be a second test later this week, during an observation where it is expected to cool more slowly. PLAN ---- OBSID CAL-ER (58206) 2007:260:07:11:50, then ArLac 2007:260:13:20, HRC-I NONE CURRENT STA. PASS Support-UTC BOT EOT ---Station------ Local Time ----------------- ------------ --- --- ---------------- ---------- (Current pass, originally scheduled for 0715-0815 EDT today, was moved up earlier, so no comm this shift) MP: The SEP2407A load is out for a review at 2:00 today. S/C: There was a small gyro bias jog on Saturday, with no associated current jog. This was comparable to the one we saw last month, with no apparent ill effects.
