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 002 Issued at 2200Z on 02 Jan 2007IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity was very low. Region 933 (S03E40) has
produced only B-class activity.
IB. Solar Activity Forecast
Solar activity is expected to be very
low. There is a slight chance for an isolated C-class flare from
Region 933.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field has been unsettled to active, with a single
minor storm period observed at high latitudes. Solar wind speed
reached a peak of approximately 650 km/s today, and remains elevated
at 550 km/s due to the coronal hole high speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be unsettled to active with a chance for isolated minor
storm periods at high latitudes on 03 - 04 January due to the
coronal hole high speed stream. Expect mostly unsettled conditions
on 05 January.
