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 158 Issued at 2200Z on 07 Jun 2010IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was very low. No significant flares were
observed during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a slight chance for a C-class event over the next 3 days
(8-10 June).
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was mostly quiet over the past 24 hours with
the exception of an isolated period of unsettled conditions between
06/21Z and 07/00Z. 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 unsettled to active with an isolated period of minor
storming possible on day 1 (8 June). This activity is due to the
high speed stream from a coronal hole as well as a possible CME
arrival from a disappearing filament on 3 June. On day 2 (9 June)
the chance for active conditions early in the period exists.
Otherwise, mostly quiet to unsettled conditions are expected.
Conditions are forecasted to return to quiet on day 3 (10 June).
