Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 014 Issued at 2200Z on 14 Jan 2007

IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was at very low levels. Region 938 (N02E48) produced several minor B-class flares today and is the only spotted region currently on the visible disk.

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

IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was at quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on 15 January. Active to minor storm conditions are possible on 16 and 17 January due to a recurrent coronal hole high speed stream.
