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 068 Issued at 2200Z on 09 Mar 2007IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z Solar activity remained at very low levels. There were
no reported flares during the period. No new regions were numbered
today.
IB. Solar Activity Forecast
Solar activity is expected to continue
at very low levels.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic field was at quiet levels. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet levels on 10 and 11 March. Active to
isolated minor storm conditions can be expected on 12 March due to a
recurrent coronal hole high speed stream.
