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 2009IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity was very low. No flares were detected.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet levels during the first two days of the
forecast period (11 - 12 March). Activity is expected to increase to
quiet to active levels on day 3 (13 March) with a chance for minor
to major storm periods at high latitudes due to a recurrent coronal
hole high-speed stream.
