> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity was at very low levels. All of the
> regions on the disk were quiescent over the period. The goes x-ray
> flux at geosynchronous orbit remained below the B-level for the
> entire interval. No new regions were numbered today.
>
> Solar activity forecast: solar activity is expected to be at
> very low levels.
>
> The geomagnetic field was predominantly at quiet to unsettled
> levels.
> A brief active period occurred in the middle and high latitudes
> between 15/0300 and 0600Z. 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 throughout the period.
>
> Event probabilities 16 apr-18 apr
>
> Class M 05/05/05
> Class X 01/01/01
> Proton 01/01/01
> PCAF green
