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 45 Issued at 2200Z on 14 Feb 2016IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z 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
14/1926Z from Region 2497 (N12W48). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (15 Feb, 16 Feb,
17 Feb).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
456 km/s at 14/0422Z. Total IMF reached 7 nT at 14/0818Z. The maximum
southward component of Bz reached -5 nT at 14/0641Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to minor storm levels on days one and three (15 Feb, 17
Feb) and quiet to active levels on day two (16 Feb). Protons have a
slight chance of crossing threshold on days one, two, and three (15 Feb,
16 Feb, 17 Feb).
