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 9 Issued at 2200Z on 09 Jan 2016IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z 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 on days one, two, and three (10 Jan,
11 Jan, 12 Jan).
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 539 km/s at
08/2332Z. Total IMF reached 6 nT at 09/2011Z. The maximum southward
component of Bz reached -4 nT at 09/0556Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 3899 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one and two (10 Jan, 11 Jan) and quiet to
minor storm levels on day three (12 Jan).
