Spacecraft Status
We remain in normal/vigorous decimation mode. Spin rate is 14.9. Cold plate 2 and CPC temperatures are being affected by the long spacecraft days (99 K and 60 C respectively).
Detector 8 showed further bouts of high noise, the latest one being at 13:30UT on the 23rd. This was around the time the HV was lowered by 6 steps to 189 although whether it was before or after is not yet clear.
