Testing on OFLS 9.1 has started unlinked batch runs. The duration issue mentioned a few days ago has been resolved. In previous releases, mostly minimum durations were scheduled; rarely was one expanded. In this version, mostly nominal durations are scheduled, with sometimes an expanded one. This represents progress, but not final success. S/C: The short eclipse went well. We reached 33.06 V max. on the batteries. It lasted ~19 min, about 30s longer than predicted. There were also some command reject counter increments. GOT: OP04 failed with memory write error. A SIMM is to be replaced. There was a Lucky crash yesterday. The OC cell phone is not taking incoming calls - being investigated. SOT: Radiation is high and increasing, ~1/10 of alert level. High energy protons have peaked and are descending. OTG auto-retract software test report (Bill Podgorski). All but one of the non-failure cases were successfully completed on ASVT last week. Ten of eleven failure cases were run, but still need to be run for record. The work appears to be on schedule for completion before the end of February. Meetings MP will meet with SOT MP and ASCDS to discuss handling star data from OFLS 9.1.
