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 157 Issued at 2200Z on 05 Jun 2004IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was at very low levels. Region 621
(S14W28) became more simplified during the period with a continued
decay in the sunspot area and further weakening of the regions beta
magnetic configuration. Although Region 625 (S12W82) is now
spotless, it managed to produce a minor B-class flare at 05/0604Z.
Regions 626 (N05W06) and 627 (S08E30) were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low levels.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels throughout the period.
