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 310 Issued at 2200Z on 06 Nov 2014IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M5 event observed at
06/0346Z from Region 2205 (N15E46). There are currently 6 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate
with a chance for X-class flares on days one, two, and three (07 Nov, 08
Nov, 09 Nov).
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
575 km/s at 05/2123Z. Total IMF reached 6 nT at 06/1137Z. The maximum
southward component of Bz reached -6 nT at 06/2047Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (07 Nov,
08 Nov, 09 Nov). Protons have a slight chance of crossing threshold on
days one, two, and three (07 Nov, 08 Nov, 09 Nov).
