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 242 Issued at 2200Z on 29 Aug 2004IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity remains at very low levels. Region 663
(N07W59) has undergone little change, and remains a magnetically
simple Beta-class region. Region 666 (N16E38) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels through 01 Sep. Chances for some C-class and
greater activity will increase on 01 Sep with the return of Region
656.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field has been 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 remain at quiet to unsettled levels through 01 Sep.
