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 1 Issued at 2200Z on 01 Jan 2014IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M9 event observed at
01/1852Z. There are currently 7 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate
with a chance for X-class flares on days one, two, and three (02 Jan, 03
Jan, 04 Jan).
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
607 km/s at 01/2100Z. Total IMF reached 17 nT at 01/1334Z. The maximum
southward component of Bz reached -13 nT at 01/1334Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (02 Jan) and quiet to
unsettled levels on days two and three (03 Jan, 04 Jan). Protons have a
slight chance of crossing threshold on days one, two, and three (02 Jan,
03 Jan, 04 Jan).
