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 149 Issued at 2200Z on 29 May 2006IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity was very low. No new regions were
numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field was mostly quiet. A period of unsettled
conditions was observed from 28/2100Z to 28/2400Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled on 30 - 31 May, with isolated
active periods possible on 31 May. Unsettled to active conditions
are expected on 01 Jun, with isolated periods of minor and major
storm conditions possible due to a recurrent coronal hole high speed
stream.
