E1300=0.8, P4GM=571.8. Ascending through 46065 km. ACIS focal plane temperature -116.0 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Two supports in the last 24 hours. No problems, all data dumps current. No loads uplinked, on-board load good until 124:13:40. APR0602B products, including the X-ray flasher TOO, were circulated yesterday. Load review today at 2pm EDT. Simulation event yesterday proceeded very well. The spacecraft was recovered out of the safe hold. There was a solar array resolver angle limit trip yesterday, but we were observing near the edge of the allowed range so this was not unexpected.
