Descending through 62028 km. ACIS focal plane temperature -119.5 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Ten supports over the weekend, no DSN issues. Uplinked 5 load segments, on-board loads good until 16:12:30. Ran three CAP's: 820 to disable auto unload of angular momentum, 675 to enable SCS 107 prior to resuming observations, and 903 to start a manual ACIS cti run. Planning for 1904A is in work but may be impacted if a DDT ten day TOO is accepted. Eclipse season starts January 18. Plan to review the contingency CAP on Wednesday. Installation of EHS 3.9.4 is now being planned starting this Thursday, 1700 to 0100 EST.
