> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity was at very low levels today. Region
> 752 (N01E43) showed slight growth during the period and a weak gamma
> magnetic structure is visible in the central sunspot cluster. This
> region was limited to low level B-class flare production. Region
> 754 (S08E51) was numbered today.
>
> Solar activity forecast: solar activity is expected to be at
> very low to low levels. Region 752 is complex enough to generate a
> C-class flare.
>
> The geomagnetic field was at quiet to minor storm levels.
> Elevated
> levels are due to a geoeffective high speed coronal hole stream.
>
> Geophysical activity forecast: the geomagnetic field is
> expected to be at predominantly quiet to unsettled levels. Isolated
> active conditions are possible on 15 april as the geoeffective high
> speed stream wanes.
>
> Event probabilities 15 apr-17 apr
>
> Class M 05/05/05
> Class X 01/01/01
> Proton 01/01/01
> PCAF green
