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 046 Issued at 2200Z on 15 Feb 2006IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity was very low. New Region 854 (S07E23)
was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field was quiet to active. Active periods were due to
the onset of a coronal hole high speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with the possibility of an
isolated active period on 16 February. On 17 and 18 February, mostly
quiet conditions are expected.
