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 34 Issued at 2200Z on 03 Feb 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
02/2204Z from Region 1967 (S13E01). There are currently 4 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 Feb, 05
Feb, 06 Feb).
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 469 km/s at
03/0009Z. Total IMF reached 8 nT at 03/0028Z. The maximum southward
component of Bz reached -6 nT at 03/1327Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on day one (04 Feb), quiet to unsettled
levels on day two (05 Feb) and quiet levels on day three (06 Feb).
Protons have a slight chance of crossing threshold on days one, two, and
three (04 Feb, 05 Feb, 06 Feb).
