SOLAR AND GEOPHYSICAL ACTIVITY INDICES FOR 24 SEPTEMBER, 2007
-------------------------------------------------------------

NOTE: The greater than 2 MeV electron fluence was moderate today.

The background x-ray flux was below class A1.0 levels.

SYNOPSIS OF ACTIVITY
--------------------

             Solar activity was very low.  The visible solar disk
       remains spotless.

            Solar activity forecast:  solar activity is expected to be very
       low.

            The geomagnetic field ranged from quiet to active with a period of
       minor storming observed at middle latitudes.  An elevated solar wind
       speed due to a coronal hole high speed stream contributed to the
       activity.  Solar wind speed remains elevated at approximately 620
       km/s at the time of issue.  The greater than 2 mev electron flux at
       geosynchronous orbit reached high levels today.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be quiet to unsettled with a chance for active periods
       on 25 september due to the ongoing coronal hole high speed stream. 
       Expect quiet to unsettled conditions on 26 - 27 september.
