Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 173 Issued at 2200Z on 22 Jun 2009
IA. 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).
