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 063 Issued at 2200Z on 04 Mar 2009IA. Analysis of Solar Active Regions and Activity from 03-2100Z to 04-2100Z Solar activity was very low. No flares were observed.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 03-2100Z to 04-2100Z
Geomagnetic field activity was at quiet to unsettled levels. Field
activity increased to unsettled levels during 04/0000 - 0300Z. ACE
solar wind measurements indicated the increase was associated with a
period of sustained southward IMF Bz combined with enhanced IMF Bt
and a modest increase in velocities.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at mostly quiet levels during the period (05 - 07
March).
