> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity was at very low levels. Region 747
> (S07W04) continued to show growth in sunspot area. Region 748
> (N09E33) went unchanged today. No new regions were numbered today.
>
> Solar activity forecast: solar activity is expected to remain
> at very low levels.
>
> The geomagnetic field was at quiet levels today. The greater
> than 2
> mev electron flux at geosynchronous orbit reached high levels.
>
> Geophysical activity forecast: the geomagnetic field is
> expected to be at predominantly unsettled to active levels
> throughout the period. Isolated minor storming may be possible on 3
> and 4 april. The expected elevated conditions are due to a
> recurrent coronal hole high speed stream.
>
> Event probabilities 03 apr-05 apr

> Class M 01/01/01
> Class X 01/01/01
> Proton 01/01/01
> PCAF green
