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 062 Issued at 2200Z on 03 Mar 2009IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity was very low. No flares were observed
during the past 24 hours and the solar disk continues to be
spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was quiet during the past 24 hours. A weak
sudden impulse occurred at 03/0602Z in response to a discontinuity
in the solar wind observed at ACE at 0451Z; solar wind speed
increased from around 320 km/s to about 350 km/s. Nonetheless the
slight elevation of solar wind speed was not sufficient to produce
activity above the quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next three days.
