Solar Activity
Some activity, including M flares
How many GOES flares occurred?
Flares above B, C, M, X class were 24 37 4 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 14 22 3 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 9 10 2 0
There were RHESSI flares/GOES flares 181 / 65 over the time range 09-Feb-16 16-Feb-16
Memory Management
Decimation was active/vigorous for the full time period. Both front and rear detectors are off during SC night, except for 4 minutes on either side. The SSR was at 0.4% at the end of today's passes.
Spacecraft Status
The cold plates, 1 and 2 are at 134.4 and 132.8 K
Data Gaps
No VC1 Gaps
VC3 Gaps GAPS IN APP_ID = 102 (VC3-MONITOR RATES) WITH PACKET RATE LT 30

Detector issues
Detectors 2 and 4 are unsegmented, Detectors 3, 6, 8 and 9 are off.
D4 - On Feb 11, we lowered the front slow threshold from 0xA0 to 0x80 for an orbit. No effect on the memory was noted. 2 small flares occurred during this orbit
2016-042-17:12:29 /IDPUTABLE4 OFFSET=FRONTSLOWDAC 2016-042-17:12:55 /IDPLOAD VALUE=0x80 ; was 0xA0
2016-042-18:53:53 /IDPUDUMPTABL TABLE=DIBTBL4 2016-042-18:54:02 /IDPLOAD VALUE=0xA0 ; was 0x80
