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 174 Issued at 2200Z on 23 Jun 2010IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z Solar activity was very low. Region 1082 (N26W52)
produced isolated low-level B-class activity. At 23/1712Z, SOHO
EIT-195 EUVI imagery observed a possible eruption along a filament
channel centered near N40E50.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels with a slight chance for an isolated C-class
event.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet on day one (24 June). Field activity is
expected to increase to mostly unsettled levels, with isolated
active periods, late on day two (25 June) and a slight chance of an
isolated minor storm on day three (26 June). This increase in
activity is due to a recurrent coronal hole high speed stream that
is forecasted to become geoeffective.
