Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 305 Issued at 2200Z on 01 Nov 2007

IA. Analysis of Solar Active Regions and Activity from 31/2100Z

to 01/2100Z: Solar activity was very low. No flares were detected.

The visible disk was spotless.

IB. Solar Activity Forecast: Solar activity is expected to be very

low.

IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z:

The geomagnetic field was quiet. The greater than 2 MeV electron flux

at geosynchronous orbit was high.

IIB. Geophysical Activity Forecast: The geomagnetic field is

expected to remain quiet through the period.
