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 178 Issued at 2200Z on 27 Jun 2006IA. Analysis of Solar Active Regions and Activity from 26-2100Z to 27-2100Z Solar activity was very low. Region 897 (N06E44) has
developed in complexity and is now a Cai beta-gamma group.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. Region 897 may produce C-class activity.
IIA. Geophysical Activity Summary 26-2100Z to 27-2100Z
The geomagnetic field has been quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be unsettled to active on 28 - 29 June due to a coronal
hole high speed stream. Expect mostly quiet conditions on 30 June.
