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 245 Issued at 2200Z on 01 Sep 2008

IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z

Solar activity was very low. The visible solar disk remained spotless.
IB. Solar Activity Forecast
Solar activity is expected to remain very low.
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to remain quiet for days one and two (2-3 Sep), becoming quiet to unsettled by day three (4 Sep) in response to an approaching recurrent coronal hole high speed stream.
