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 166 Issued at 2200Z on 15 Jun 2007IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity was very low. The visible solar disk
remains spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field ranged from quiet to active. The solar wind
speed has been decreasing through the day, but remains slightly
elevated due to the coronal hole high speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet throughout the forecast period.
