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 034 Issued at 2200Z on 03 Feb 2007IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity was very low. No flares were observed
during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a chance for an isolated C-class event.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was mostly quiet during the past 24 hours. The
greater than 2 MeV electron flux reached high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be predominantly quiet for the next three days (4-6
February)
