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 215 Issued at 2200Z on 03 Aug 2003IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity has been low-moderate. Region 424
(S18E52) continues to generate minor C-class flare activity, and
produced an impulsive M1.3 x-ray flare at 02/2354 UTC. A new Region
427 (N04W16) has grown quickly over the last 24 hours, but remains
relatively inactive.
IB. Solar Activity Forecast
Solar activity is expected to be low.
Regions 424 (S18E52) and 427 (N04W16) have only a slight chance of
producing an M-class x-ray flare.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field has been at unsettled to active levels. The
coronal hole driven high-speed stream has passed beyond geoeffective
range. The greater than 2 MeV electron flux at geosynchronous
orbit reached very high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at unsettled levels for the next three days.
