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 092 Issued at 2200Z on 02 Apr 2007

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

Solar activity has been very low.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic field was active with periods of minor storming due to a recurrent coronal hole high speed stream. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be unsettled to active on April 3 and quiet on April 4 & 5.
