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 069 Issued at 2200Z on 10 Mar 2003IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity remained at low levels. The largest
flare of the period was a C2.0/Sf event that occurred at 10/1754Z
from Region 310 (S16W62). This region has been in decay throughout
the period. Region 306 (N05E34) was responsible for lesser B-class
flares and has also shown some decay. Most of the spotted regions
were quiescent during the period. New Region 312 (N09W25) was newly
assigned today.
IB. Solar Activity Forecast
Solar activity is expected to be at
low levels.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was at predominantly quiet to unsettled levels.
An isolated active period occurred at mid and high latitudes
between 10/1200 and 1500Z. The greater than 2 MeV electron fluxes
at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels through the first 48
hours of the period. Day three should experience active conditions
due to a co-rotating interactive region that has preceded a
recurrent coronal hole over the past several rotations.
