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 159 Issued at 2200Z on 08 Jun 2010IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a slight chance for a C-class event for the next 3 days
(9-11 June).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was mostly quiet with the exception of an
isolated unsettled period between 1500-1800Z. 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 be mostly quiet to unsettled with an isolated period of
active conditions likely early on day 1 (9 June). Conditions are
forecast to be quiet on days 2 and 3 (10-11 June).
