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 32 Issued at 2200Z on 01 Feb 2016IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
01/0114Z. 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 on days one, two, and three (02 Feb,
03 Feb, 04 Feb).
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic

wind speed, as measured by the ACE spacecraft, reached a peak speed of
366 km/s at 01/1005Z. Total IMF reached 11 nT at 31/2108Z. The maximum
southward component of Bz reached -9 nT at 31/2108Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (02 Feb, 04
Feb) and quiet to active levels on day two (03 Feb).
