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 319 Issued at 2200Z on 15 Nov 2010IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity was low. Region 1124 (N14W30) produced a
C2/Sf event at 15/0728Z. This region has grown in area and number
of spots throughout the period.
IB. Solar Activity Forecast
Solar activity is forecast to be low
with C-class flares likely for the next 3 days (16-18 November).
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field was mostly quiet with isolated periods of
unsettled conditions at mid and high latitudes. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels during
the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly unsettled to active with a slight chance for
an isolated period of minor storming over the next 3 days (16-18
November). This activity is forecast because of elevated solar wind
speeds near 650 km/s and intermittent periods of southward Bz, as
well as a possible glancing blow from the CME on 13 November.
