Solar activity report

Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 009 Issued at 2200Z on 09 Jan 2007

IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z

Solar activity was very low. Region 933 (S06W56) developed several new spots in the northwestern portion of the spot group. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very low with a chance for isolated C-flare activity from Region 933.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic field was quiet. 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 mostly quiet.
