Solar Activity

Very quiet this week, except for a few flares in the high Bs in the past day or so.

How many GOES flares occurred? 

 Flares above B, C, M, X class were      2     0     0     0

RHESSI flare list contains 0 over the time range 03-Jan-17 10-Jan-17

No overlapping RHESSI flares to count, sorry

Memory Management

Decimation was changed to Normal/Vigorous (from quiet/vigorous) last Wednesday. : 

2017-004-21:38:11 start idpu_dec_normal_vigorous

The SSR has been hovering near the 20% level at the end of pass sets, and is set to be much lower than that at the end of today's set. It was peaking at ~35% at beginning of the pass set, meaning that there was a bit of decimation going on some of the time.

Detectors 3 and 9 are recording events during spacecraft day, and for 4 minutes prior to and after daylight.


Spacecraft Status

Detectors 3 and 9 are recording events.

Cryocooler power has been turned dow to ~75 W: 

2017-004-21:34:14 start icryomain_ramp(75)

To avoid pesky shutter motions due to the ever-increasing detector 3f deadtime (which currently controls attenuator motions). The attenuator logic has been disabled: 

2017-004-21:37:35 /idpudisarm ale  ; logic disabled
2017-004-21:37:46 /iattmove move=out1 ;thick out
2017-004-21:37:56 /iattmove move=out2 ;thin out

...and both attenuators are locked out. We need to be mindful of this when solar activity picks up.
