Tohban report, 2005/08/01 to 2005/08/08

1) Solar Activity:

Flare activity originated mainly from a decaying AR#10792 (which
produced the X-class flare last week) and an emerging AR#10794.
AR#10792 produced a few M class flares in the beginning of the week
and is now content with producing C-class flare along with its
partner AR#10794.  The background level remained near B1.  

How many GOES flares occurred?
  Flares above B, C, M, X class were     41    14     4     0
And how many of these are listed in the RHESSI flare list?
  Flares above B, C, M, X class were     17     7     2     0
And how many had EXCELLENT coverage?
  Flares above B, C, M, X class were     15     3     1     0

There were RHESSI flares/GOES flares          52 /           59
over the time range 31-Jul-05 07-Aug-05

More C-class flares are expected while the chance for M class is 
now only 20%.

3) Memory Management:

The SSR fill level began the week at 57%, and with several active regions currently 
on the near-side of the Sun, another memory deletion had been proposed.  Based on
the position of the read pointer, it was decided that a data deletion would insure
little or no decimation for a possible X-class flare.  Unfortuantely, it was found out
to the Tohban's dismay that data deletions are NOT possible without the direct input from 
either Mark and Jeremy.  Since they were both on the east coast and being that the data deletion 
was only decided as a safeguard, we therefore decided to take a chance and not delete data.
Fortunately (or perhaps not), no X-class flares occurred and solar activity has been diminishing
since then therefore memory has slowly decreased to it's current level of approx. 13%.

4) Data Gaps:

There were a bunch of data gaps but only in the last few days so perhaps they will
be filled(?).  These may be related to the power outage yesterday.

5) Decimation.
We're in the NORMAL/VIGOROUS mode. 
Front segment data are not being taken during S/C night.

6) Other issues:
G2 is now segmented since the voltage was lowered.  The voltage
on G5 and G6 will be lowered today (08/08/05).  

The Tohban list has been updated.  Tohban reports should only
be sent to tohban@ssl.berkeley.edu
