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 150 Issued at 2200Z on 30 May 2006

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z

Solar activity was very low. Region 886 (N08W53) developed during the past 24 hours and is now a Cro Beta group with a size of 40 millionths. Region 891 (S13E19) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain very low.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was quiet to unsettled with an isolated minor storm period from 1200 - 1500 UTC.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled on 31 May. Mostly unsettled condtions with active periods are expected on 01 - 02 June due to a recurrent coronal hole high speed stream.
