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 335 Issued at 2200Z on 30 Nov 2016IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
29/2338Z from Region 2615 (S08E51). There are currently 3 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, two, and three (01 Dec, 02 Dec, 03 Dec).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 431 km/s at 30/0142Z. Total IMF reached 6 nT at
30/1715Z. The maximum southward component of Bz reached -3 nT at
30/1816Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 22208 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (01 Dec, 02 Dec, 03
Dec).
