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 2007IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity was very low. No flares occurred. New
Region 966 (S04E74) rotated into view today and is a simple, H-type
sunspot group.
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. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the past 24
hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next two days (4-5 August). Conditions
should be mostly quiet on day 3 (6 August) but an increase to
unsettled is possible late in the day due to the onset of a high
speed solar wind stream.
