CAPs - next passes 2140, 0600 VCDU rollover today at 1456 There was a problem with one uplink - CPA (command processor) failure; commands caused errors. The station replaced the CPA but there is now one additional error in the OBC. MP: Another Dec1800 load review today 2pm after a few additions were made yesterday. Work has started on the Dec25 2 week load. It contains HETG and LETG observations. We will attempt to schedule the LETG observations for after Jan. 1. S/C: - GOT: The patch for the script hang-up problem is due at OCC today, and testing on the 3rd string is planned for the 3rd shift tonight. If all goes as planned, it will be presented to the FDB for approval tomorrow at 2 pm. SOT: Radiation is low. ASCDS: several QLs. The Grinch lost his grip, and we have color back.
