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 2008IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity was very low. The visible solar disk
remains spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field was quiet. The solar wind data as measured at
the ACE spacecraft indicated signatures of a solar sector boundary
crossing between 29/1330Z to 29/1530Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next three days (30 August - 01
September).
