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.

SDF Number 7 Issued at 2200Z on 07 Jan 2013

IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C3 event observed at 07/0852Z from Region 1640 (N28W87). There are currently 12 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be at low with a chance for moderate levels on days one, two, and three (08 Jan, 09 Jan, 10 Jan).
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
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 385 km/s at 07/1934Z. Total IMF reached 6 nT at 07/0126Z. The maximum southward component of Bz reached -5.8 nT at 07/0327Z.
