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 2 Issued at 2200Z on 02 Jan 2016

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M2 event observed at 02/0011Z from Region 2473 (S21W89). There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on day one (03 Jan) and expected to be very low with a chance for a C-class flares on days two and three (04 Jan, 05 Jan).
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
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 511 km/s at 02/1313Z. Total IMF reached 9 nT at 02/0132Z. The maximum southward component of Bz reached -6 nT at 02/0102Z. Protons greater than 10 MeV at geosynchronous orbit reached a peak level of 21 pfu at 02/0450Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 4113 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to major storm levels on day one (03 Jan), quiet to active levels on day two (04 Jan) and quiet to unsettled levels on day three (05 Jan). Protons greater than 10 Mev are expected to cross threshold on day one (03 Jan) and have a chance of crossing threshold on day two (04 Jan).
