Solar Activity

The solar activity was extremely low, remained at B-level throughout the week. There is only one AR on disk, and so the solar activity is expected to remain low next week.

How many GOES flares occurred?

 Flares above B, C, M, X class were      3     0     0     0

And how many of these are listed in the RHESSI flare list?

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

And how many had EXCELLENT coverage?

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

There were RHESSI flares/GOES flares 7 / 3 over the time range 18-Oct-16 25-Oct-16

Memory Management

The SSR was at 0% at the end of BGS passes.

Spacecraft Status

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

There were some relatively large data gaps (as shown below) in addition to numerous short (300 s) gaps (not shown).

Detector issues

Detectors 3 and 9 are powered on, and are recording events. The D9 rear fast threshold was raised from 0x80 to 0xA0.
