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 2004

IA. 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.
