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
::::::::::Corrected Copy:::::::::: SDF Number 083 Issued at 2200Z on 24 Mar 2010IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was at very low levels for the past 24
hours. Region 1057 (N17E57) has showed steady growth throughout the
day and is classified as a D type group. The total sunspot area
increased to about 240 millionths in size near the end of the
period. Region 1056 (N17W50) decayed to spotless plage. No new
regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low to low levels with C-class flares likely from Region 1057. There
is a slight chance for M-class events also from Region 1057.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels for the next two days
(25-26 March) due to the arrival of a weak coronal hole high-speed
stream. The geomagnetic field is expected to return to quiet levels
on day three (27 March) as the effects of the coronal hole subside.
