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 2015 *** CORRECTION***

IA. 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 C3 event observed at 10/1411Z from Region 2443 (N07W95). There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (11 Nov, 12 Nov, 13 Nov).
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field has been at active to major storm levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 766 km/s at 10/1505Z. Total IMF reached 12 nT at 09/2112Z. The maximum southward component of Bz reached -9 nT at 09/2254Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 3 pfu at 10/0020Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 19551 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to minor storm levels on days one and two (11 Nov, 12 Nov) and unsettled to active levels on day three (13 Nov).
