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 160 Issued at 2200Z on 09 Jun 2010IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z Solar activity was very low. Region 1078 (S21W60) has
grown in size and magnetic complexity over the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low with a chance for a C-class event from Region 1078 during
the next 3 days (10-12 June).
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic field was quiet 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
forecast to be mostly quiet with a chance for an isolated period of
unsettled conditions during the next 3 days (10-12 June).
