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 249 Issued at 2200Z on 06 Sep 2010IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity has been low. Region 1105 (N19W64)
produced a C2/Sf flare at 06/1459Z.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field has been quiet to active. An isolated active
period occurred between 06/0300-0600Z. Solar wind, as measured at
the ACE spacecraft, indicated a 10 nT enhancement of the total field
with the Bz component reaching around -8 nT during the enhanced
activity interval. The greater than 2 MeV electron flux at
geosynchronous orbit briefly reached high levels during the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the two days (07-08 September), and quiet
to unsettled on day three (09 September).
