One stored command segment uplinked, on-board loads good until 281:02:35 (finishes OCT0107A). OCT0807B products are out for email review today. CAP 425G, the EIA sequencer self-test ran nominally yesterday, and results were as expected. ACE data flow has resumed as of yesterday. Soft protons are at background counting rates.
