this is a note file for science run interruption occured on 12/06/2006

The trigger level for E1300 is changed from 10 to 20, and this is the first interruption with 20.

From 12/06/2006 SOT shift Report
--------------------------------
Solar radiation levels rose yesterday in response to repeated flare activity from active region 930
(two X-class, one M-class and numerous C-class flares). SCS 107 ran autonomously yesterday afternoon at 
2006:340:16:16Z. This trip was probably due to an E1300 combination of actual radiation and current-limit effect.


RADIATION SUMMARY
----------------

Radiation levels are very high (P3 > 9000 at 341:12:00Z) and still rising steeply. Continued flare and CME
activity are expected from region 930.

3-day Solar-Geophysical Forecast issued Dec 6 at 22:00 UTC

Solar Activity Forecast: Solar activity is expected to be high. Region 930 is expected to produce M-class 
flares and there is a good chance for further X-class activity.

Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active on 
07 - 08 December with a chance for periods of minor or major storm conditions due to the recurrent 
coronal hole high speed stream. Quiet to unsettled conditions are expected on 09 December. 
The greater than 10 MeV proton event is expected to continue for at least another 24 hours

From 12/08/2006 SOT Shift Report
---------------------------------
Solar radiation levels are extremely high (P3 ~ 65,000) but very slowly decreasing. We are not currently
observing. 

RADIATION SUMMARY
----------------

Radiation levels are extremely high (P3 > 65,000 at 342:12:00Z) but slowly decreasing. Flare and CME
activity are still possible from region 930.

3-day Solar-Geophysical Forecast issued Dec 7 at 22:00 UTC

Solar Activity Forecast: Solar activity is expected to be moderate to high. Region 930 is expected to produce 
further M-class flares and there is a good chance for X-class activity.

Geophysical Activity Forecast: The geomagnetic field is expected to range from unsettled to minor storm levels 
with a chance for major storm periods for the next three days (08 - 10 December). Although the magnetic cloud 
associated with the X9 flare and CME observed on 05 December is not expected to impact earth, a shock passage is 
likely; consequently, active to minor storm periods are expected on 08 December. CME activity associated with the 
M6 and X6 flares on 06 December is expected to cause occasional major storm periods late on 08 December and 09 December. 
Disturbed conditions are expected to continue through 10 December. The greater than 10 MeV proton event is expected 
to continue through 09 December. The greater then 100 MeV proton event appears to have peaked and, barring another 
injection of high energy protons, the event should end on 08 December.

Radiation:
- The ACE and GOES radiation levels have been continuing a slow but
  steady decline (but see below) since the last of large flares from 
  region 930.  That sunspot region has produced only minor C-class
  flares in the last 2.5 days.
- In the last 6 hours there is evidence for a sharp uptick in the softest
  ACE proton channels including P3.  The noisy signature initially looked
  like backscatter, but this may be real.
- Current rates support a return to science.
- Solar Activity Forecast: Solar activity is expected to be low with a chance
  for M-class activity from Region 930.
- Geophysical Activity Forecast: The geomagnetic field is expected to be
  quiet to active on 11 December. On 12 and 13 December, conditions are
  expected to be quiet to unsettled. The greater than 10 MeV proton event is
  expected to end in the next 24 to 48 hours.
