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 054 Issued at 2200Z on 23 Feb 2003IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z Solar activity was very low. No flares occurred as the
disk is marked by just two spotted regions.
IB. Solar Activity Forecast
Solar activity is expected to be low.
Region 290 (N18W21), quiet today, may produce an occasional C-class
event.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was quiet to active. The solar wind radial
speed remains elevated, gusting between 550 and 650 km/s. The
energetic electron flux at geosynchronous orbit reached high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly unsettled. Periodic active conditions may
occur, pending a decline in the solar wind speed.
