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 034 Issued at 2200Z on 03 Feb 2012IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity was at very low levels. The disk and
limb was quiet and stable with no Earth-directed CMEs observed
during the period.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low for the next three days (04 - 06 February).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field was at quiet to unsettled levels with isolated
high latitude active periods due to the waning effects of a
geoeffective coronal hole high speed stream. During the period, ACE
satellite observations indicated wind speeds averaged about 425 km/s
while the Bz component of the interplanetary magnetic field varied
between +/- 5 nT.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at mostly quiet levels for the next three days (04 -
06 February).
