Solar Activity
Very quiet. A single flare above B level. GOES baseline is about A4 or A5.
Memory Management
SSR fill was at 0% at end of pass set.
Spacecraft Status
Detectors 3 & 8 are on.
See http://sprg.ssl.berkeley.edu/~ayshih/soh/latest_temperatures.pdf
for a summary plot of recent temperatures, efficiencies and accelerometer values.
Data Gaps
None of consequence.
Downlink issues
Overall better, now that cryocooler power has been diminished. Still concerning, and we only have two detectors on. The issue seems to arise when the receiver temperature is high (we only have a combined transmitter/receiver temperature reading available to us).
