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 029 Issued at 2200Z on 29 Jan 2008IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity was very low. New Region 892 (S09E53)
was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for 30-31 January. Quiet to unsettled
conditions with isolated active periods are expected for 01 February
as a recurrent coronal hole becomes geoeffective.
