Solar Activity

It was another quiet week. There are four active regions on the disk and nothing major about to rotate on. A few days ago there was a flurry of C flares, but that AR quickly rotated off. A new AR about to come on-disk is produced an occulted B flare, but quiet activity is expected to continue.

How many GOES flares occurred?

 Flares above B, C, M, X class were     24    19     1     0

Memory Management

The SSR emptied after most pass set.

Spacecraft Status

A spin-up from 14.6 to 15.0 RPM was performed on 2013-086 between 18:23 and 19:30 UT.

Data Gaps

There is one data gap in VC3 data that cannot be replayed due to the SSR fill issue (?)

GAP START TIME GAP END TIME GAP (SEC) 2013-04-02T23:55:00.000 -- 2013-04-03T00:00:00.000 300.00000

Detector issues

The detector 5 monitor rate remains elevated (as high as that of detector 2).

Other notes

The problem of quicklook generation processing has been fixed.

Decimation	Normal/vigorous
HLAT Decimation	Rear decimation weight 6, no front decimation
Night time data (fronts)	+/- 4 minutes
Night time data (rears)	Taking data at nights
Require extra passes?	No
Requirement for moving pointer?	No
Attenuator operation	Normal
Detector problems?	Detector 5 arc + extended noise period.
