SYNOPSIS OF ACTIVITY
--------------------
Solar activity was very low. No flares occurred during
the past 24 hours. Region 971 (N03W06) is a small C-type sunspot
group and was quiet and stable.
Solar activity forecast: solar activity is expected to be very
low.
The geomagnetic field was at active to minor storm levels from the
beginning of the period through 29/1200Z, and was mostly unsettled
thereafter. Real-time solar wind observations at ace show that the
activity was due to the ongoing influence of a high speed solar wind
stream from a coronal hole. The greater than 2 mev electron flux at
geosynchronous orbit reached high levels during the past 24 hours.
Geophysical activity forecast: the geomagnetic field is
expected to be mostly unsettled for the first day (30 september)
with a chance for isolated active periods. Activity should decline
to quiet to unsettled for the second and third days (01-02 october).
