RHESSI Tohban report, 2-Mar-2008 to 9-Apr-2008

1. Solar Activity

The 3 ARs rotated off the disk by 20:00 05-Apr-2008 and so back to solar 
min quiet Sun with GOES flat-lining below A-class. Looks like its going to 
be quiet for a while (from stereo B).

There were about 7 B-Class flares before then, (RHESSI only cuaght then 
ones about 06:00 3-Apr and 11:00 5-Apr) and there was a C-Class flare than 
RHESSI also caught (01:15 3-Apr-2008).


2. Memory Management

Fine, down to 0% at end of passes. Still Normal/Active.

3. Data Gaps

Some on the 3rd?


4. Spacecraft Operations

Given that it was quiet we did a test run of the shutter experiment to 
investigate the systematics in the background spectrum. The thick shutter 
was moved in/out 08:51:27 to 08:56:27 and 09:01:27 to 09:06:27 on 9-Apr. 
It seems to work and as the sun is still quiet we will probably try to run 
this further over the next week.
