Solar Activity

Not much. How many GOES flares occurred?

 Flares above B, C, M, X class were      8     9     0     0

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

 Flares above B, C, M, X class were      5     7     0     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were      3     2     0     0

There were RHESSI flares/GOES flares 128 / 17 over the time range 10-Feb-15 17-Feb-15

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 is empty at the end of the BGS pass set each day.

Spacecraft Status

The cold plates, 1 and 2 were at 127.9 and 126.7 K, at 2015-02-18 18:52 The solar array temperature (1) and the Cryocooler power converter temperature are consistently above their yellow limits, at 101 and 52 C, respectively.
