> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity remains at very low levels. Regions 747
> (S07E23) and 748 (N09E59) are both hsx alpha spot groups that were
> numbered today. Region 745 (N11W80) continues a slow decay and is
> now spotless.
>
> Solar activity forecast: solar activity is expected to
> continue
> at very low levels.
>
> The geomagnetic field was at quiet to unsettled levels. The
> greater
> than 2 mev electron flux at geosynchronous orbit reached high levels
> today.
>
> Geophysical activity forecast: the geomagnetic field is
> expected to be at quiet to unsettled levels through 1 april.
> Isolated minor storming conditions are expected late on 2 april due
> to the onset of a recurrent coronal hole high speed stream and
> should continue through 3 april.
