The Sun was very quiet this week. GOES went only once above B level (for a B1 flare).


Memory Management

Ending near 0% at end of pass set.

Spacecraft Status

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

= Detector issues

D6f has a very low livetime (<10%). But it might be one of those temporary (few days) dip. Let's keep observing, to see if it gets back up.


Spacecraft Management

Decimation Active/Vigorous
HLAT Decimation Rear decimation
Night time data (fronts) plus/minus 4 minutes from daylight
Night time data (rears) plus/minus 4 minutes from daylight
Require extra passes? No
Requirement for moving pointer? No
Attenuator operation logic enabled
Detector problems? See notes above.
