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 5 Issued at 2200Z on 05 Jan 2015IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
05/1747Z from Region 2253 (S07W18). There are currently 5 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
days one, two, and three (06 Jan, 07 Jan, 08 Jan).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 589 km/s at 05/1911Z. Total IMF reached 15 nT at 05/0711Z. The
maximum southward component of Bz reached -10 nT at 04/2152Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on day one (06 Jan), quiet to unsettled
levels on day two (07 Jan) and unsettled to active levels on day three
(08 Jan). Protons have a slight chance of crossing threshold on days
one, two, and three (06 Jan, 07 Jan, 08 Jan).
