Solar Activity

The Sun was very active produced a string X-flares this week!!

HSI_TOHBAN_FLARE_COUNTER: No RHESSI Flares for this time period

Below A5 the whole week, except today: a whopping B2 flare!

Memory Management

Ending at ~25% at end of pass set.

Spacecraft Status

Detectors 1, 3, 6 and 8 are active and taking data.

Data Gaps

No apparent data gaps so far, but with the SSR full, we are lagging far behind.
