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 104 Issued at 2200Z on 14 Apr 2010IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was very low. There were no flares
observed during the last 24 hours. Region 1062 (S18W34) has decayed
to spotless plage.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next three days (15-17 April).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field was quiet during the last 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain quiet for the next three days (15-17 April).
Revised estimates for yesterdays partial-halo CME speed indicate a
probable arrival of the flank of the CME at Earth sometime on 18
April.
