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 2010IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z Solar activity has been at very low levels for the past
24 hours. Several B-class events were produced by new Region 1081
(N22W43), which was numbered early in the period today and has a
beta magnetic classification.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low levels with a chance for a C-class event for the next three
days (12-14 June).
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours.
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 at quiet levels for the next three days (12-14
June).
