> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity was very low. Today's activity consisted
> of occasional B-class flares. Most of these were from region 751
> (S07W84). However, sxi images indicate a small, bright active region
> on the east limb at N01 which was the source for a B8 event at 1814
> utc.
>
> Solar activity forecast: solar activity is expected to be very
> low. There is a slight chance for an isolated C-class event during
> the next 3 days (11-13 april).
>
> The geomagnetic field was quiet. The greater than 2 mev
> electron flux
> at geosynchronous orbit was at high levels.
>
> Geophysical activity forecast: the geomagnetic field is
> expected to be quiet until sometime late on 11 april when conditions
> are expected to increase to mostly active levels due to a coronal
> hole. Active conditions from the coronal hole are expected to
> continue for 12-13 april.
>
> Event probabilities 11 apr-13 apr
>
> Class M 05/05/05
> Class X 01/01/01
> Proton 01/01/01
> PCAF Green
