Solar Activity

Very quiet week. A few B-class flares.

How many GOES flares occurred?

 Flares above B, C, M, X class were     11     0     0     0

RHESSI flare list contains 0 over the time range 13-Feb-18 20-Feb-18

No overlapping RHESSI flares to count, sorry

Memory Management

Thanks to additional passes, SSR is down. Currently at 53.7%, with 4 passes still to go today.

Unfortunately, BGS is down today, and possibly for longer -- we'll be getting only three passes a day for some time, and the SSR is expected to creep up fast. It has been decided to turn off the very noisy D6.

Spacecraft Status

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

Data Gaps

No apparent data gaps until Feb 18th, where there are some orbit-long holes. This, and the lack of data after the 19th, is likely due to the SSR still being quite full.

Detector issues

None

Other notes

The State-Of-Health packet counter flag in the RHESSI status page turned red quite often this week... Jim thinks this happens when AGO passes are not recorded properly. No adverse effects that we can observe, though.

No State-of-Health plots (those controlled by Ops) since Jan 22, 2018.

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.
