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 066 Issued at 2200Z on 07 Mar 2007IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was very low. Region 944 has rotated
off the visible disk. Region 945 (S07W56) no longer exhibits
visible spots. At approximately 07/0100Z a slow moving CME was
observed on the west limb apparently from the backside. Due to the
position and speed of this CME it is not expected to be
geoeffective.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field has been unsettled to active. Solar wind speed
remains elevated near 600 km/s due to a recurrent coronal hole high
speed stream. 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 quiet to unsettled 08 - 10 March .
