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 058 Issued at 2200Z on 27 Feb 2006IA. Analysis of Solar Active Regions and Activity from 26-2100Z to 27-2100Z Solar activity has been very low. A new region was
numbered today as Region 856 (S08E69). This region has been the
source of several low level B-class flares in the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 26-2100Z to 27-2100Z
The geomagnetic field has been at quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet. Periods of unsettled conditions on 28
February are possible due to coronal hole affects.
