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 55 Issued at 2200Z on 24 Feb 2016IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z 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
24/1229Z from Region 2506 (S07E48). 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 (25 Feb,
26 Feb, 27 Feb).
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 374 km/s at 24/0734Z. Total IMF reached 7
nT at 24/0857Z. The maximum southward component of Bz reached -6 nT at
23/2142Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1937 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (25 Feb,
26 Feb, 27 Feb).
