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 036 Issued at 2200Z on 05 Feb 2007IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z 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 slight chance for an isolated C-flare during the next
three days (6-8 February).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was predominantly quiet during the past 24
hours. A solar sector boundary crossing was noted today in the solar
wind data reported by ACE. The greater than 2 MeV electron flux
reached high levels during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next three days (6-8 February)
