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 8 Issued at 2200Z on 08 Jan 2016IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 6 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one and two (09 Jan, 10 Jan) and expected to be very low
with a chance for a C-class flares on day three (11 Jan).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
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
611 km/s at 08/0140Z. Total IMF reached 5 nT at 08/1355Z. The maximum
southward component of Bz reached -4 nT at 08/1014Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 5724 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (09 Jan,
10 Jan, 11 Jan).
