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 2013

IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z

Solar activity has been at very low levels for the past 24 hours. There are currently 7 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be at low levels with a slight chance for M-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 levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 322 km/s at 03/1909Z. Total IMF reached 5.5 nT at 03/1220Z. The maximum southward component of Bz reached -3.3 nT at 03/1209Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels for the next three days (04 Jan, 05 Jan, 06 Jan).
