Solar Activity

Very quiet...!


Memory Management

SSR fill was at 60% on Monday, and rapidly crept up to ~78% on Wednesday, due lack of passes.

Spacecraft Status

Detectors 3 and 8 are recording events.

See:

http://sprg.ssl.berkeley.edu/~ayshih/soh/latest_temperatures.pdf

for a summary plot of recent temperatures, efficiencies and accelerometer values.

Data Gaps

Due to high SSR fill, there is little data for this week that has been downloaded.

Detector issues

Detectors 3 and 8 are powered on, and are recording events. No threshold changes or HV changes this past week.
