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 169 Issued at 2200Z on 18 Jun 2010IA. Analysis of Solar Active Regions and Activity from 17-2100Z to 18-2100Z Solar activity has been very low.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 17-2100Z to 18-2100Z
The geomagnetic field has been quiet. Solar wind data from the ACE
spacecraft indicates the continuation of a high speed solar wind
stream, with wind speeds generally decreasing and reaching about
around 500 km/s at the end of the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet.
