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 162 Issued at 2200Z on 11 Jun 2007

IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z

Solar activity was very low. Region 960 (S05W59) produced several B-class flares during the past 24 hours. The largest of these was a B8/Sf at 10/0027Z.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet on 12-13 June. Expect unsettled to active conditions, with isolated minor storm periods at high latitudes, on 14 June as a coronal hole rotates into a geoeffective position.
