Emerge from perigee, then do obsid 5727, an ACIS-S observation of the blazar 87GB 1143+4437, and obsid 6267, an ACIS-S observation to look for inverse Compton scattering in the high power radio lobes of 3C 325.

EPH temp 73.88 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Two 26m supports completed, no issues. One load segment uplinked, on-board loads are good through 108:04:50. The routine CAP 563A was run to diagnose the CPE warm start count, and gave the expected value of 1. APR1805B products are ready to circulate for review. A TOO has been approved which will cause issue of load interrupt products later today, and subsequent revision of the APR1805 week. ACE P3 rates are at their background level. Solar activity expected to be very low over the next three days.
