NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports, no issues. On-board loads good until 171:09:55. JUN2303A products out this morning, load review this afternoon. IRU A1 current holding steady at ~125ma. Some yellow temperature limits reached on the ACA secondary mirror and the redundant focal plane. These can be attributed to the lower focal plane temperature and the increased thermo-electric cooler power. These limits were deliberately set low based on operation of the ACA at -10 deg C, and are not a concern. Radiation zone planning telecon today at 3pm, 405 244 5060 1165#.
