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 072 Issued at 2200Z on 13 Mar 2010IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity was at very low levels for the past 24
hours. Region 1054 (N15E15) showed growth and is now magnetically
classified as a Beta-Gamma. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low to low levels for the next three days (14-16 March).
C-flares are likely from Region 1054. There is a slight chance for
an isolated M-class event from this region.
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was at quiet levels for the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at mostly quiet levels on the first day (14 March)
and then at mostly quiet to unsettled levels on day two and three
(15-16 March) due to a recurrent coronal hole high-speed stream and
solar sector boundary crossing.
