Solar Activity

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

Memory Management

Ending at 1-2% level at end of pass set.

Spacecraft Status

Detectors 1, 3, 6 and 8 are active and taking data. Detector deadtime thresholds for attenuator contorl were increased from 18% to 21% this week.

Data Gaps

DATA GAPS FOR 2017/12/01
TIME RANGE: 2017-12-01T00:00:00.000 -- 2017-12-02T00:00:00.000
NO GAPS IN APP_ID = 1 (VC1-SOH)
GAPS IN APP_ID = 154 (VC1-PMTRAS) WITH PACKET RATE LT 4
N_GAPS           1
GAP START TIME              GAP END TIME                   GAP (SEC)
2017-12-01T15:00:00.000 -- 2017-12-01T15:45:00.000       2700.0000
NO GAPS IN APP_ID = 102 (VC3-MONITOR RATES)

Detector issues

Nothing new.

Misc

A "sunrise" pass was taken this week, where battery data taken at much higher rate than usual.

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
Ref. deadtime for Att.thresholds	21.0%
Detector problems?	No.
