RHESSI Tohban report, 14-Jun-06 to 21-Jun-96
Hugh Hudson, hhudson@ssl.berkeley.edu

1. Solar Activity

Activity was extremely low, approaching the low levels of early 2006,
although some flares occurred early in the week.  At present a tiny soft 
X-ray bright patch is present near disk center.

How many GOES flares occurred?
  Flares above B, C, M, X class were     18     3     0     0

2. Memory management

Memory usage drifted up during the Crab operations, due perhaps to
particles or to special operational settings. Present levels at first
GBS are beginning to exceed 50%. Luckily the Crab Nebula is not known to
produce giant flares.

4. QL survey 

* Rather amazing features at 17-Jun 16:02. No solar reports of odd
activity, but is this something unusual we can see because we are
offpointed?. See
http://sprg.ssl.berkeley.edu/~tohban/browser/?show=grth+qlpr+monfs&date=20060617&time=160709 
* 18-jun 07:00 also noted, see

* G5 glitches being attended to by David.

5. Crab Nebula

Crab operations were very successful - Hurford and Fivian said "lucky";
Hudson said "software functional". We can only tell which one by seeing if it's
this easy next year. RHESSI was within half a degree of the Crab
position by June 14 (we should start earlier next year). Bryna Hazleton
has succeeded in determining centroids from the coarse collimators,
which generally confirm the FSS calibration even for 5 degrees
elongation. As of end of BGS early 21-Jun we were about 0.35 degrees from
the Crab.
