RHESSI Tohban report, 8-Oct-2006 to 15-Oct-2006

1. Solar Activity

Activity was low but not negligible: some well-observed B-class flares. 
You may yawn, but these could have been observed by Hinode and may be
among our most important yet. They are on 12-Nov and have short time
scales and hard spectra.

How many GOES flares occurred?
  Flares above B, C, M, X class were     50     9     0     0
And how many of these are listed in the RHESSI flare list?
  Flares above B, C, M, X class were     16     5     0     0
And how many had EXCELLENT coverage?
  Flares above B, C, M, X class were     14     2     0     0
 
There were RHESSI flares/GOES flares          65 /           59
over the time range 06-Nov-06 13-Nov-06

NOTE: the above automated summary missed badly this time. We did not
get two C-class flares with "EXCELLENT" coverage. The author of this
bad code has been informed.

2. Memory Management

For reasons that are not so clear, memory has not been a problem this
week or for the previous couple of months. My theory is that solar
minimum results in substantially reduced particle precipitation events.

3. Data Gaps

08-Nov 11:05-13:40
13-Nov 19:30-20:10 garbage data
14-Nov 00:15-01:40 garbage data

4. Spacecraft Operations

At 01:09:20 UT 8-Nov RHESSI decimation state was changed back to
"Normal_active" in conclusion of the Murcury transit.  Just as a note 
the SSR reached only 14.5% full.

"We went to spin up mode for about 2 orbits yesterday, We started at
317-23:19:50 UT, at a rate of 14.5 RPMs, and ended at 318-01:30:00 UT
(15.05 RPMs)" - Jeremy

5. Hinode

It is probably time for us to get seriously interested in Hinode
observations. It appears that everything is working fine, and we should
expect to see very relevant data from all of the instruments. In the
short term XRT (the soft X-ray telesope - like Yohkoh's SXT but higher
resolution) and the EIS (XUV imaging spectroscopy) will be most
interesting. We do not know yet how well these instruments can observe
flares, but there are high hopes.

I spoke with Leon Golub on the phone and we agreed that we should try
hard to work together on RHESSI/Hinode comparisons. He will be at AGU
and I will probably visit Japan very briefly soon. The views of the XRT
data I have seen are very encouraging.

6. Data survey highlights 

11-Nov 10:15 catalog miss -
12-Nov 09:10 inexplicable night-time activity, maybe axion storm
12-Nov 19:50 catalog miss +
13-Nov 13:44 possible GRB
