Solar Activity

Solar activity was low with only B and C class flares in the past week. NOAA 11465 has just today been classified as beta-gamma so this region may begin to produce larger flares. There are 11 active regions on disk in all, although at least three are on the west limb and may not be observable any more. Stereo B shows that there are a number of regions approaching the eastern limb in the southern hemisphere in the coming days.

How many GOES flares occurred?

 Flares above B, C, M, X class were     11    38     0     0

And how many of these are listed in the RHESSI flare list?

 Flares above B, C, M, X class were      9    26     0     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were      6    14     0     0

There were RHESSI flares/GOES flares 356 / 49 over the time range 18-Apr-12 25-Apr-12

Memory Management

During the week the SSR was emptying by end on the week, reaching a maximum of ~35%.

Spacecraft Status

This morning Renee and I successfully changed the thresholds for detectors G2, G3 and G9 to the values stated. We followed that by setting the IDPU load address to a safe address. The commanding was through BGS at

On 111/15:32 UTC the following commands were sent to change detector G2's front slow threshold to 0x60 and detector G2's front fast threshold to 0x80, also was decided to change detectors G3 and G9's rear fast threshold to 0x60.

• DIB2
  • /IDPUDUMPTABL DIBTBL2
  • /IDPUTABLE2 FRONTSLOWDAC ;Load address 0x25B9
  • /IDPULOAD VALUE=0x60 ;Byte 7, Front Slow threshold
  • /IDPULOAD VALUE=0x80 ;Byte 8, Front Fast threshold

• DIB3
  • /IDPUDUMPTABL DIBTBL3
  • /IDPUTABLE3 REARFASTDAC ;Load address 0x25C9
  • /IDPULOAD VALUE=0x60 ;Byte 10, Rear Fast threshold

• DIB9
  • /IDPUDUMPTABL DIBTBL9
  • /IDPUTABLE9 REARFASTDAC ;Load address 0x262C
  • /IDPULOAD VALUE=0x60 ;Byte 10, Rear Fast threshold

• Set IDPU load address to a safe address
  • /IDPUADRH HIGH=0x72
  • /IDPUADRL LOW=0x00

• Start isetdpaddr_spectmp
