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 167 Issued at 2200Z on 16 Jun 2006IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z Solar activity was low. Region 892 (S06, L=290)
produced a C2.8 at 16/1423 UTC.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
The geomagnetic field was quiet to active. Solar wind speed at ACE
has decreased from approximately 600 km/s to 520 km/s. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
