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 288 Issued at 2200Z on 15 Oct 2006IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity was very low. The 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 has been quiet to active. Solar wind speed has
been decreasing throughout most of the day as the coronal hole
rotates out of a geoeffective position.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled for the next three days (16 - 18
October).
