* D6 fast rates are a bit high (have been rising slowly over the past week).  It would be a good idea to raise the front fast threshold a touch.  I didn't want to do this at the same time as the slow threshold experiment!

* A note for the new tohban: the light leak problem continues, and most of the wild departures in the monitor rate plots are from these.  The problem is worst in detectors 2, 3, 5, and 9, but also shows up in some of the others.  Remember that for D2 this shows up in the fronts because it's unsegmented, while the others usually manifest in the rears.

Solar Activity

Solar activity is moderate to high and is picking up. There are 9 active regions on the disk, with 2-3 of them flaring. Many of these are coming from AR 12268 at disk center, including an M class flare. There is also a prolific AR rotating onto the disk; this AR produced many flares on its last turn on the merry-go-round and is already showing activity this time around.

These statistics are from Tuesday afternoon; I'll update on Wednesday afternoon.

How many GOES flares occurred?

 Flares above B, C, M, X class were     12    31     1     0

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

 Flares above B, C, M, X class were      6    21     0     0

And how many had EXCELLENT coverage?

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

There were RHESSI flares/GOES flares 229 / 44 over the time range 19-Jan-15 26-Jan-15

Memory Management

We've recently switched to Active / Vigorous decimation, at 2015-028-18:06 UT this morning. Due to increased activity in the past ~day, the SSR is no longer emptying, and was at 35% this morning (before the pass set).

Spacecraft Status

Data Gaps

No gaps this week as of Jan 27 (Tuesday).

Spacecraft Management

A spin-up was performed on Monday, Jan 26 from about 14.5 RPM to 14.97 between 20:29 and 22:06 UTC. There were no anomalies.
