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 156 Issued at 2200Z on 05 Jun 2009IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z
Solar activity was very low. No flares occurred during
the past 24 hours. Region 1019 (N24W23) appears to be slowly
decaying and was quiet and stable.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low for the next three days (06-08 June).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was mostly quiet. There was one unsettled
period from 05/0900-1200Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain quiet for the next three days (06-08 June).
