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 249 Issued at 2200Z on 05 Sep 2016

IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

Solar activity has been at very low levels for the past 24 hours. There is currently one numbered sunspot region on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low with a chance for C-class flares and a slight chance for an M-class flare on days one, two, and three (06 Sep, 07 Sep, 08 Sep).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 748 km/s at 04/2346Z. Total IMF reached 6 nT at 05/1847Z. The maximum southward component of Bz reached -5 nT at 05/1628Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 56842 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to active levels on day one (06 Sep) and quiet to unsettled levels on days two and three (07 Sep, 08 Sep).
