RHESSI Tohban Report, July 14 to July 21, 2003

Hugh Hudson

(1) Solar activity

There was high activity in the sense of C-class flares, as summarized
below, but nothing big. 

There is now a program "hsi_tohban_flare_counter" to be found on the
tohban home page. This program summarizes the GOES flare occurrence
and shows which had full RHESSI coverage. It checks the observing
summary for each GEV event and took about ten minutes to run, yielding

How many GOES flares occurred?
Flares above C, M, X class were           72           0           0
And how many had good RHESSI coverage?
Flares above C, M, X class were           34           0           0

Here "good coverage" means that the entire interval, start to end by
GOES definitions, had neither SAA nor orbit night. 

(2) Memory management

Memory usage gradually crept downwards over the week, getting below
30% at first BGS pass at least once.

(3) Data gaps

None the tohban is aware of

(4) Science note

With key help from Richard, the tohban systematically compared RHESSI
low-energy temperatures with GOES temperatures. GOES looks too low by
something like 3 MK in this comparison. Richard comments that a NEAR
spectrum he has looked at suggests that the GOES high channel is 
signficantly under-reported.

(5) Homework

The tohban began to make nice graphical representations of how the
decimation works.
