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 081 Issued at 2200Z on 22 Mar 2009IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z Solar activity was very low. No flares or sunspots were
observed during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field was predominantly quiet. Unsettled conditions
were observed at mid-latitudes between 22/03-06Z. The continued
influence of the recurrent coronal hole is reflected in ACE solar
wind observations. Velocities ranged between 386-472 km/s, and
interplanetary Bz ranged from -3 nT to +7 nT.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be predominantly quiet for the next three days (23-25
March).
