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 215 Issued at 2200Z on 02 Aug 2016IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
on day one (03 Aug) and expected to be very low with a slight chance for
a C-class flare on days two and three (04 Aug, 05 Aug).
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 459 km/s at 02/1715Z. Total IMF reached 20
nT at 02/2058Z. The maximum southward component of Bz reached -16 nT at
02/2005Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 906 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (03 Aug), unsettled to
active levels on day two (04 Aug) and quiet to active levels on day
three (05 Aug).
