Tohban report, 12-dec-2005 to 19-dec-2005
R. Schwartz and H. Hudson, hhudson@ssl.berkeley.edu

1. Solar Activity: Low, with scattered C-class flares. Currently a large
EFR is near disk center, producing beaucoup microflares and growing up to be
a real active region.

How many GOES flares occurred?
  Flares above B, C, M, X class were     51     5     0     0
And how many of these are listed in the RHESSI flare list?
  Flares above B, C, M, X class were     11     2     0     0
And how many had EXCELLENT coverage?
  Flares above B, C, M, X class were      7     0     0     0
 
There were RHESSI flares/GOES flares          29 /           56
over the time range 11-Dec-05 18-Dec-05

Don't be alarmed that RHESSI sees fewer; _we_ require 12-25 keV to call
it a flare.
 
2. Memory Managment:

SSR has been getting to zero prior to the last BGS pass, in spite of the
extra SAS usage (see item 4).

3. Data Gaps:

13-Dec 22:00 poor data quality (many dropouts), two orbits
16-dec 23:00-23:35
18-dec 01:36 orbit missing from QL

4. Special operations

As an experiment, we are accumulating SAS data with higher cadence and
with 6 pixels (rather than the usual 4). The data should be used to see,
in a statistical sense, if we can effectively determine parameters
describing limb darkening as well as limb position. This operation
commenced 2005-349-17:00 UT (Dec. 16) and probably can run for a while,
since the SSR is in excellent state.

16-dec-05, A1 remained enabled for no obvious region through two entire
orbits.

Need to spin up.
