1. Solar Activity

The GOES base level was mostly in the low B's with very low activity. 
Together with a slight rise of the base level, there were 24 hour periods
with somewhat higher activity (Mar 24, 27 and 29) producing burst of
serveral higher C-class flares and M-class flares.

To be mentioned are two M-class flares with good RHESSI coverage
(Mar 24 and Apr 5) and a C-class flare with a very long duration
decay phase of appr 12 hours (Mar 31).

Statistics are as follows:

How many GOES flares occurred?
  Flares above B, C, M, X class were     54    46     3     0
And how many of these are listed in the RHESSI flare list?
  Flares above B, C, M, X class were     25    31     3     0
And how many had EXCELLENT coverage?
  Flares above B, C, M, X class were     19    15     2     0
 
There were RHESSI flares/GOES flares         206 /          103
over the time range 23-Mar-04 05-Apr-04
 

2. Decimation

Normal/Normal all week.


3. Memory Management

Not an issue. SSR level between 0-40% for the whole time range.


4. Data Gaps

None.


5. Special incident: ADP exception

At 2004-03-27 14:11 UT, the ADP stopped sending telemetry packets.
Although the cause is not fully understood yet, the data aquisition
program on the ADP seemed to hang. A reset of the processor brought
the system back to normal operation.

Data gap in aspect data: 2004-03-27 14:11 UT to 2004-03-30 03:30 UT
