PRELIMINARY SOLAR & GEOPHYSICAL INDICES FOR 01 SEPTEMBER, 2010
--------------------------------------------------------------

      DRAO 10.7 cm Solar Flux at 18Z, 20Z, 22Z: N/A, N/A, N/A sfu.
          Predicted Solar Flux for Next 3 Days: 76, 76, 77.
                     Average 90-day Solar Flux:  78.
               Current Middle Latitude A-Index:   3
                     Current Boulder K-Indices: 1111 012*
                   Current Planetary K-Indices: 1000 022*
                Boulder A-Index 3-Day Forecast:   5,   5,   5.

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

             Solar activity has been at very low levels for the past
       24 hours. Region 1101 (N12W32) and region 1102 (N26W52) grew in
       areal coverage but remained stable and quiet. New regions 1103
       (N25W32) and 1104 (N24W27) developed late in the period and are both
       magnetically classified as beta groups.

            Solar activity forecast:  solar activity is expected to be at
       very low levels with a slight chance for C-class events for the next
       three days (02-04 september).

            The geomagnetic field has been at quiet levels for the past 24 hours.
       The greater than 2 mev electron flux at geosynchronous orbit was at
       high levels throughout the period.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be at quiet levels for the next three days (02-04
       september).
