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 2007

IA. 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 .
