> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity continues at very low levels. A new
> region rotating around the east limb at S05 may have been the source
> of a cme observed off the southeast limb at around 22/0630Z. The few
> sunspot groups on the visible disk are small and stable, and
> exhibited no significant changes or activity this period.
>
> Solar activity forecast: solar activity is expected to be very
> low to low. A new region rotating around the east limb at S05 may
> elevate activity levels slightly on 24 and 25 april.
>
> The geomagnetic field was quiet to unsettled.
>
> Geophysical activity forecast: the geomagnetic field is
> expected to be quiet to unsettled with occasional active periods. A
> weak disturbance is expected on 22 and 23 april as a recurrent
> coronal hole high speed stream rotates into a geoeffective position.
>
> Event probabilities 23 apr-25 apr
>
> Class M 01/01/01
> Class X 01/01/01
> Proton 01/01/01
> PCAF green
