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 3 Issued at 2200Z on 03 Jan 2014IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z
Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
02/2218Z from Region 1944 (S08E64). There are currently 9 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be moderate
with a chance for X-class flares on days one, two, and three (04 Jan, 05
Jan, 06 Jan).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
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
655 km/s at 02/2138Z. Total IMF reached 5 nT at 03/2024Z. The maximum
southward component of Bz reached -4 nT at 03/1452Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 990 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (04 Jan) and quiet levels
on days two and three (05 Jan, 06 Jan). Protons have a slight chance of
crossing threshold on days one, two, and three (04 Jan, 05 Jan, 06 Jan).
