ACE 2 hr fluence is 2.3e6 vs. threshold 3.6e8. CRM-based orbital fluence is 9.9e6 vs. threshold 1.0e9. Chandra is in the magnetosphere. 4) Quick Look data review (OK unless noted): There were no new quick look data in this shift. 5) Failed guide star. During obsid 61808, it was noted that the OBC rejected one guide star, with AGASC ID 490220520, because it was too bright. The AGASC ACA magnitude is 7.63, and the ACA-reported magnitude is 5.43. 6) The HRC EGSE at the OCC was not receiving realtime telemetry. Despite recycling the realtime telemetry connections on the HRC EGSE and on SQUIRT, and despite restarting the HRC monitoring software RTCADS, the problem remains. 7) There will be no SOT Lead support at the OCC, for both morning and afternoon shifts, during the week Dec 25 - Jan 1. SOT Lead personnel will be on call during this time period. Contact numbers for the SOT Leaders are available, as always, at: http://asc.harvard.edu/mta/COORDINATION/internal/pocs.html
