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 006 Issued at 2200Z on 06 Jan 2008IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z 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.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field was mostly unsettled with some isolated active
periods during the past 24 hours. The solar wind speed remained
elevated throughout the period and showed characteristics consistent
with a high speed stream from a coronal hole. 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 unsettled with a chance for active periods for the
first day (07 January). Conditions are expected to decline to quiet
to unsettled for the second day (08 January) and should be
predominantly quiet for the third day (09 January) as the high speed
stream is expected to subside.
