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 195 Issued at 2200Z on 14 Jul 2014IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z 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
14/1246Z from Region 2109 (S08W86). 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 (15 Jul,
16 Jul, 17 Jul).
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
390 km/s at 14/1514Z. Total IMF reached 15 nT at 14/2058Z. The maximum
southward component of Bz reached -5 nT at 13/2112Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on day one (15 Jul) and quiet to
unsettled levels on days two and three (16 Jul, 17 Jul).
