> SYNOPSIS OF TODAYS ACTIVITY
> ---------------------------
>
> Solar activity was very low. No new regions were
> numbered today.
>
> Solar activity forecast: solar activity is expected to be very
> low to low.
>
> The geomagnetic field was quiet to unsettled. Solar wind speed
> at
> ace continued to decline over the period from approximately 500 km/s
> to 420 km/s. The greater than 2 mev electron flux at geosynchronous
> orbit was at high levels again today.
>
> Geophysical activity forecast: the geomagnetic field is
> expected to be quiet to unsettled on 08 and 09 april. On 10 april,
> quiet to active conditions are expected due to the effects of a
> recurrent coronal hole high speed stream.
