Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 309 Issued at 2200Z on 04 Nov 2008
IA. Analysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: Solar activity was low. Region 1007 (N36W52) produced a C1.0 flare at 0330Z.
IB. Solar Activity Forecast: Solar activity is expected to be very low to low. Region 1007 has a chance of producing another C-class flare.
IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic field was at quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet on days one and two (05-06 November). Unsettled to active conditions are expected on day three (07 November) due to a recurrent coronal hole high-speed solar wind stream.
