Solar Activity
The solar activity was very low: a few low-B flares. A large coronal hole was present at the beginning of the tohban week, but has since rotated off the disk. Low (6%) probability of >C flare activity in the next day, according to solar monitor.
How many GOES flares occurred?
Flares above B, C, M, X class were 13 0 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 2 0 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 2 0 0 0
There were RHESSI flares/GOES flares 16 / 3 over the time range 18-Oct-16 25-Oct-16
Memory Management
The SSR has bee creeping up: now about 30% at end of pass set.
Spacecraft Status
D9f livetime is slowly decreasing, now at 80% level. D9r livetime has been plummeting, even with an increase in fast thresholds from 0xA0 to 0XB0. Recommend to increase BOTH front and rear by another 0x10.
There is only one BGS pass per day these days (the rest are AGO), so it is a bit more difficult to closely monitor the detectors.
%The spacecraft has remained stable. Detectors 3 and 9 continued %recording events. The cold tips temperature have come down further, %and they are currently 117.6 and 115.9 K as of 2016-10-26. The cold %plates, 1 and 2 are 142.0 and 140.8 K.
Data Gaps
Very large data gaps on Nov 1 and Oct 31 -- probably not processed yet.
Some important gaps:
GAPS IN APP_ID = 102 (VC3-MONITOR RATES) WITH PACKET RATE LT 30 N_GAPS 2 GAP START TIME GAP END TIME GAP (SEC) 2016-10-28T02:10:00.000 -- 2016-10-28T02:15:00.000 300.00000 2016-10-28T05:00:00.000 -- 2016-10-28T06:50:00.000 6600.0000
Detector issues
Detectors 3 and 9 are powered on, and are recording events. The D9 rear fast threshold was raised from 0xA0 to 0xB0.

Notes
Spacecraft Management
| Decimation | Normal/Vigorous |
| HLAT Decimation | No decimation |
| Night time data (fronts) | full-time |
| Night time data (rears) | full-time |
| Require extra passes? | No |
| Requirement for moving pointer? | No |
| Attenuator operation | Working as expected |
| Detector problems? | See notes above. |
