> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity continues at very low levels. There are
> currently no sunspots on the visible disk. Occasional B-class flares
> were associated with activity in a new region rotating on the east
> limb near S05. This region was the likely source of cme activity on
> 22 april.
>
> Solar activity forecast: solar activity is expected to be very
> low to low. The new region rotating on the southeast limb may
> elevate activity levels.
>
> The geomagnetic field was quiet to unsettled with isolated
> active
> periods. A weak recurrent coronal hole high speed stream continues.
> Solar wind speed is elevated to near 550 km/s, but the imf bz is
> weak and predominantly northward.
>
> Geophysical activity forecast: the geomagnetic field is
> expected to be quiet to unsettled with isolated active periods on 25
> april. Expect mostly quiet conditions on 26 and 27 april as the
> current high speed solar wind stream subsides.
>
> Event probabilities 25 apr-27 apr
