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 085 Issued at 2200Z on 26 Mar 2010

IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z

Solar activity was very low. Region 1057 (N15E30) has grown in size and increased in classification to a Dki Beta. New Region 1058 (N25W21) remains stable and quiet as a Axx Alpha spot. A filament was observed lifting off the SW quadrant of the disk around 26/07Z. An associated weak limb event CME is visible on LASCO C3 coronagraph imagery.
IB. Solar Activity Forecast
Solar activity is expected to be low with C-class flares likely, and a slight chance for an M-class flare over the next three days (27-29 March).
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled with the possibility of an isolated active period over the next 3 days (27-29 March).
