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 39 Issued at 2200Z on 08 Feb 2016IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z 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
08/0529Z from Region 2492 (N14W19). There are currently 5 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (09 Feb,
10 Feb, 11 Feb).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
