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 288 Issued at 2200Z on 15 Oct 2014IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity was at moderate levels. The period began above
the M1 threshold, while in recovery from the M2 flare at 14/2121 UTC,
from a region around the East limb. No other flares occurred during the
period. There are currently 7 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (16
Oct, 17 Oct, 18 Oct).
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 580 km/s at 15/0040Z. Total IMF reached 15 nT at 14/2213Z. The
maximum southward component of Bz reached -12 nT at 14/2344Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on day one (16 Oct) and quiet to
unsettled levels on days two and three (17 Oct, 18 Oct).
