Contents

Solar Activity

Very quiet... GOES baseline level was ~A3, increased a little bit (A5) with the appearance of an active region over the eastern limb.


Memory Management

SSR fill has been slowly creeping up (~2% per day). Currently at 71%.

Spacecraft Status

Still annealing.

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 no downlinked data for the past three days. No VC-3 data prior to that (normal, detectors are off), but we are getting VC1-SOH and VC-1 (PMTRAS).

Detector issues

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