RHESSI Tohban report:  June 21 to June 29, 2006

1. Spacecraft Operations

The period began during Crab offpointing operations with RHESSI
well-pointed at the Crab (within 0.5 degrees) as it had been since 14
June 06:14.  It's position was monitored daily with preliminary Crab
imaging agreeing well with the FSS pointing information.  After more
than 9 days of good Crab data had been obtained, it was commanded back
to the Sun at 23 June 11:20 UT.  By June 24 14:00 UT, the Sun had been
reacquired. At that time, spinup was initiated to raise the spin rate
from 14.3 rpm to 15.0.

Normal solar observations resumed at 24 June 21:10 UT.

2.  Solar Activity

Solar activity throughout this period was very low, with baseline levels
below A1 early in the period rising to ~A7 at the end.  Flare activity
was limited to B-class events as shown below:

How many GOES flares occurred?
   Flares above B, C, M, X class were     23     0     0     0
And how many of these are listed in the RHESSI flare list?
   Flares above B, C, M, X class were      6     0     0     0
And how many had EXCELLENT coverage?
   Flares above B, C, M, X class were      3     0     0     0

There were 			          37 /           23
RHESSI/GOES flares over the time range 21-Jun-06 30-Jun-06


3. Memory Management

The SSR fill peaked at 65% on June 23 but was gradually reduced to a low
of 5% by the end of this period.


4. Data Gaps

There were four substantial data gaps on June 21 and 22:
a 100 minute gap in SOH and PMTRAS data June 21 02:45-04:15;
a 150 minute gap in VC3 June 21 15:35-17:40
a 165 minute gap in VC3 June 22 07:30-10:15
a 90 minute gap in VC3 June 22 11:40-13:10
