EPH temp: 96.12 degF EPH 27V: 17.08 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Ten supports over the weekend. On a DSS-27 pass it took three attempts to enable commanding to the spacecraft, reason unknown. Three segments of the OCT0107A commands were uplinked. ON-board loads good until 278:11:31. OCT0807 products will be out tomorrow. There was a Gyro 2 Unit 2 current jog, of a total of about 10ma (4 bits) up to 108 ma over 4 hours, with a small associated bias jogs in pitch and yaw. This is the first current "jog" seen in gyro 2, although the current has occasionally been this high earlier in the year. TEIO hit a yellow high limit at 152 deg F. ACE soft protons are at background level and solar activity is expected to continue very quiet over the next few days.
