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 303 Issued at 2200Z on 29 Oct 2016IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z
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
with a slight chance for a C-class flare on days one, two, and three (30
Oct, 31 Oct, 01 Nov).
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic
field has been at unsettled to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 740 km/s at 29/0842Z. Total IMF
reached 10 nT at 29/0216Z. The maximum southward component of Bz reached
-9 nT at 29/0054Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 21657 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at unsettled to active levels on days one and two (30 Oct, 31 Oct)
and quiet to active levels on day three (01 Nov).
