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 195 Issued at 2200Z on 14 Jul 2010IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was low. Region 1087 (N20E08) produced
two C-class events. The first was a C1 flare at 14/1230Z and the
second was a C3 flare at 14/2047Z. 1087 is a Dso group with a
beta-gamma magnetic configuration and has shown little change in
areal coverage and spot number during the last 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. There is a slight chance for an isolated M-class event
from Region 1087.
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field was mostly quiet. The solar wind monitor on
the ACE spacecraft indicated a sector boundary crossing into a
positive sector at approximately 14/0900Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be unsettled with a chance for isolated active periods
on day one (15 July) due to a coronal hole high speed stream. Quiet
conditions are expected to return on days two and three (16-17
July).
