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 126 Issued at 2200Z on 06 May 2009IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity was very low. No flares were detected.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be quiet to unsettled, with a chance for isolated active
levels at high latitudes, on day one (07 May) due to a recurrent
coronal hole high-speed stream. Predominately quiet levels are
expected on days two and three (08 - 09 May) as the effects of the
high speed stream decrease.
