> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity was low. Region 745 (N12E03) produced a
> C1/sf flare at 24/2344Z. This region is in a slow growth phase with
> minor magnetic mixing. No other significant activity was observed on
> the solar disk or limb.
>
> Solar activity forecast: solar activity is expected to be low
> to very low. An isolated C-class flare is possible from region 745.
>
> The geomagnetic field was quiet to active with isolated minor
> storm
> periods at high latitudes. The most disturbed geomagnetic conditions
> followed short periods of southward imf bz to near -10 nt. A high
> speed coronal hole stream rotated into a geoeffective position over
> the past 24 hours. Solar wind speed began the period at just over
> 400 km/s, but increased to near 700 km/s by the end of the period.
>
> Geophysical activity forecast: the geomagnetic field is
> expected to continue at quiet to active levels. Minor storm periods
> are possible at high latitudes on 26 march. Mostly quiet to
> unsettled levels with just isolated active periods are expected on
> 27 and 28 march as the high speed solar wind stream subsides.
