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 22 Issued at 2200Z on 22 Jan 2014IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z 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
22/1905Z from Region 1955 (S14W18). There are currently 10 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 (23 Jan, 24 Jan,
25 Jan).
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
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
629 km/s at 22/0744Z. Total IMF reached 11 nT at 21/2121Z. The maximum
southward component of Bz reached -6 nT at 22/2009Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (23 Jan) and quiet levels
on days two and three (24 Jan, 25 Jan).
