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.
