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 191 Issued at 2200Z on 10 Jul 2010IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity was very low. Region 1087 (S19E57) is a
beta magnetic configuration and produced two B-class flares during
the period. The region shows occasional point brightenings and is
growing in both white light areal coverage and sunspot count.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. There is a chance for a C-class flare, and a slight
chance for a M-class event, from Region 1087.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet levels for days one and two (11-12 July).
Quiet to unsettled levels, with isolated active conditions, are
expected for day three (13 July) due to a recurrent coronal hole
high speed stream.
