NOTES/ISSUES/PROBLEMS From the 9am status meeting: No problems over the weekend, until this morning. A transmitter problem delayed AOS ~20 minutes. Comm was extended ~7 minutes and SSR dump was completed. On-board loads good until day 018:13:03. Two CAPs were run: 617 to re enable RADMON, and 775 to obtain a CTI measurement prior to resumption of the science observing program at 012:03:58:00.0. There will be a VCDU rollover at 16:37:39 today. JAN2102 products will be out later today or early tomorrow. The first email load review isn't expected until tomorrow. Gyro 1 current has been noisy the past four days. No effect on bias. ASVT testing planned tomorrow, and later in the week. After tomorrow's 9am status meeting will be a readiness review for ONLS 3.8.1 transition to ops. ACIS operations meeting tomorrow, 2:30pm in sixth floor conference room.
