RHESSI Tohban report, 2008-Jul-23 to 2008-Jul-30

1. Solar Activity

Very quiet Sun, no active regions.


2. Off Pointing

RHESSI had been in off pointing mode since June 17 and 
began the re-acquisition of the Sun on Tuesday, July 29 
at 0758 UT.  Just after re-pointing to the Sun, there 
was a spin anomaly for ~4 hours. The spin rate is currently 
stable at 14.57 rpm.

Currently, RHESSI is pointing at the Sun with normal/active 
decimation and attenuator logic enabled.


3. Memory Management

The off pointing allowed a catchup on downlinking of data 
that had piled up during the BGS downtime.  (BGS is now 
back to full operation.)  The catchup is almost complete, 
with the SSR currently 13.72% full.


4. Data Gaps:

Gaps could be due to BGS downtime.

GAPS IN APP_ID = 102 (VC3-MONITOR RATES) WITH PACKET RATE LT 30
GAP START TIME              GAP END TIME                   GAP (SEC)

2008-07-25T12:50:00.000 -- 2008-07-25T14:45:00.000       6900.0000


5. Spacecraft Operations

The cold plate temperatures have dropped down from the unusually 
high values seen in the last few months.  Current temperatures 
for cold plates 1 and 2 are 94.987 K and 93.649 K.

A request was made to bring down the HV on detector 8 by 8 steps.
