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 08 Mar 2004IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity has been low. Region 570 (S14E46)
produced a C2.3 flare at 08/2011 UTC. This region exhibited slight
growth over the past 24 hours, to an area of 750 millionths. No new
regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. Region 570 has the potential to produce C- and
isolated M-class flares.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field has been quiet to unsettled. 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 on 9 March, with increasing
activity to active and isolated minor storm conditions on 10 and 11
March. Increased activity is likely as Earth's magnetic field comes
under the influence of a high speed solar wind stream originating
from a coronal hole in geoeffective position.
