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 173 Issued at 2200Z on 22 Jun 2009IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z Solar activity was very low. Region 1023 (S22E29) was
numbered this period. The region emerged rapidly on the disk, and
was classified as a 3-spot, Bxo beta sunspot group. Only A-class
x-ray activity was observed from this region. Region 1022 (S26E01)
decayed to an Axx sunspot group. The region was quiet and stable
during the period.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next three days (23 - 25 June).
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet for the next three days (23 - 25 June).
