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 153 Issued at 2200Z on 01 Jun 2008

IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z

Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field was at quiet levels. Solar wind velocities were averaging around 560 km/s under the continued influence of the coronal hole high speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled conditions for day one (02 Jun). Quiet levels are expected for days two and three (03-04 June) as the influence of the high speed stream is expected to wane.
