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 314 Issued at 2200Z on 10 Nov 2014IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
10/0222Z from Region 2205 (N14W08). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
day one (11 Nov) and likely to be moderate with a chance for X-class
flares on days two and three (12 Nov, 13 Nov).
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic
field has been at unsettled to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 552 km/s at 10/1713Z. Total IMF reached 23 nT at 10/0201Z. The
maximum southward component of Bz reached -10 nT at 09/2308Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (11 Nov) and quiet to
unsettled levels on days two and three (12 Nov, 13 Nov). Protons have a
slight chance of crossing threshold on days one, two, and three (11 Nov,
12 Nov, 13 Nov).
