4 Other Operations Issues

Solar Activity

Happy new Year, plenty of activity. See the nugget Cycle 24 Has Begun by H. Hudson.

How many GOES flares occurred?

 Flares above B, C, M, X class were     49     6     0     0

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

 Flares above B, C, M, X class were     20     4     0     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were     12     2     0     0

There were RHESSI flares/GOES flares 42 / 55 over the time range 23-Dec-09 06-Jan-10

Memory Management

Decimation was normal/active for the week. Front segment events are turned on during eclipses. SSR is at 1.569%.

Data Gaps

Intermittent vc1 gaps remain from 17:00 UT on 29-Dec-2009, to approximately 06:00 UT on 30-Dec-2009.

Other Operations Issues

The Battery state of charge has been very low; battery 1 is below its red limit at 73.6%. Battery 2 is currently at 77.3%. Presumably this is due to shorter sunlight periods.
