1. Solar Activity: 

The new active region that came about last week has been fairly discreet, 
except for the fact that the GOES baseline level has been raised to the high Bs.
Also, a C3 flare had been caught.

How many GOES flares occurred?
  Flares above B, C, M, X class were     38     1     0     0
And how many of these are listed in the RHESSI flare list?
  Flares above B, C, M, X class were      5     1     0     0
And how many had EXCELLENT coverage?
  Flares above B, C, M, X class were      3     0     0     0
 
There were RHESSI flares/GOES flares           8 /           39
over the time range 24-Apr-07 01-May-07


2. Memory Managment:

Decimation was NORMAL/ACTIVE for the week, and we collect ECLIPSE data. 
Currently the SSR is at 3.92%. It often drops to zero after the day's last pass.
We could perhaps take an even lower setting than NORMAL for the front segments?


3. Data Gaps: 

A big (~1 orbit) data gap reported in VC1 data (SOH and PMTRAS): 
2007/04/28 ~23:35 to 2007/04/29 01:10).
Obs. summ. rates look ok for this time (normal, as we got the VC3 data)

NO GAPS IN APP_ID = 102 (VC3-MONITOR RATES)

And another datagap on the first of the month, but this one is due to a glitch, 
and the data is expected to be recovered.

4. MISC.

	a. Since January 3rd, 2007, the RHESSI Observing Times at www.solarmonitor.org no longer works.
	b. Since 2007/04/12 22:52 UT, there is no new GOES 12 data in /disks/solar/rhsi_data/sswdb/g2d 
	This is because sohoftp.nascom.nasa.gov (the site we mirror these data from) also does not have them.
	Apparently, this is due to the fact that GOES 12 has stopped sending data.
