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 177 Issued at 2200Z on 26 Jun 2006IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity was very low. Region 897 (N06E57)
produced two B1 flares during the past 24 hours. A Bright Surge on
the Limb (N03E90), reaching a height of .18 solar radius at
26/0549Z, was reported by the Learmonth Solar Observatory.
IB. Solar Activity Forecast
Solar activity is expected to be very
low. There is a chance for a C-class flare from Region 897.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled on 27 June. A recurrent coronal
hole is expected to rotate into geoeffective position on 28 Jun.
Unsettled to active conditions are expected for 28-29 June, with
minor storm periods possible on 28 June.
