Will uplink tomorrow for intercept Sat.morning. S/C: There was a dropout of the OBSID number on 108:23:09:00 for 8 VCDs. It momentarily changed to a different, but valid OBSID. We will redump the SSR for that period of time. ASVT test: hardware dump, last sequence success flag set SOPs and GRETA display error log updates were successfully tested yesterday. GOT: Support redump. SOT: Proton rates were falling, but an M class flare occurred at ~1100 UT. This came from an active region that just became visible at the solar limb. Mgr: no FDB today.
