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 127 Issued at 2200Z on 07 May 2006

IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z

Solar activity was very low. There was no activity of note in the five sunspot groups on the visible disk. All these active regions are small with simple magnetic configurations. New Region 883 (S04E56) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to continue at very low levels. There is a slight chance for a C-class flare.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field ranged from quiet to minor storm levels. The disturbed conditions were associated with a high speed coronal hole stream. Solar wind speed gradually increased to over 600 km/s following the onset of the high speed stream midday on 06 May.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to active. Isolated active periods are possible on 08 May due to a coronal hole high speed stream. Expect quiet to unsettled conditions on 09 and 10 May.
