The SSR is emptying at the end of the daily passes, max 22%. David Smith will initiate taking events at night time this week so SSR should be monitored. In addition, a hurricane is due to hit Wallops on Saturday. Greg is preempting this by switching passes to San Diago and Walheim. However, if this can't happen, Wallops may not be operable. Again, SSR should be monitored.
There were no data gaps this week.
We remain in normal/vigorous decimation mode. Spin rate is 14.8. Cold plate 2 and CPC temperatures are trending normally with the shorter day length (102.1 K and 56.2 C respectively).
Detector 8 showed further bouts of high noise, the latest one being at 13:30UT on the 23rd. Following this, the G8 HV was dropped by a further 6 steps to 189 (~1600 local, 00:00UT on the 24th).
There has been no indication of the pointing anomaly mentioned last week based on the Browser quicklook images.
An isolated spike in G3 fronts was observed here. Will consult with David.
