Solar Activity
Solar activity was low this week with only minor C class flares occurring despite the presence of a beta-gamma-delta region for much of the week. All regions on disk are currently in decay however, a large active region is just behind the east limb and may bring more activity.

Flares above B, C, M, X class were 35 8 0 0

Data Gaps
There were no data gaps this week.
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.
There has been no indication of the pointing anomaly mentioned last week based on the Browser quicklook images.
