The old run file on OFLS was deleted by accident. Due to this, the schedule had to be run in non continuity, but continuity is on for command loads. S/C: - GOT: - SOT: Radiation is high & rising. We decided to keep watching, but not intervene unless rates go up dramatically. A CME is on its way, so rates may rise.

Because this is above the threshold, we had a tagup and decided that since we are descending and will shut down in ~6 hrs, we will take no action unless this rate increases dramatically. *ACIS* Orbital fluence (since perigee)is 8.8e8 vs. threshold 1.0e9.
