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 164 Issued at 2200Z on 13 Jun 2010

IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z

Solar activity was moderate during the past 24 hours. Region 1079 (S23W95) produced an M1.0/SF flare at 0539Z which was associated with a Type II radio sweep. Regions 1079 and 1080 (S24W77) decayed to plage towards the end of the period. Region 1081 (N24W76) produced several C-class flares during the past 24 hours and maintains a beta magnetic classification.
IB. Solar Activity Forecast
Solar activity is expected to be low for days 1 and 2 (14-15 June). Activity is expected to be very low for day 3 (16 June).
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to remain quiet on days 1 and 2 (14-15 June). Conditions are expected to be quiet to unsettled with a chance for isolated active periods on day 3 (16 June) due to a recurrent coronal hole high speed stream moving into a geoeffective position.
