Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 177 Issued at 2200Z on 26 Jun 2009
IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity was very low. No flares occurred during
the past 24 hours. The solar disk was void of spots.
IB. Solar Activity Forecast: Solar activity is expected to be very
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was mostly quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for the first day (27 June). An increase to
unsettled levels with a chance for active periods is expected on the
second day (28 June) due to a favorably positioned coronal hole.
Conditions are expected to be quiet on the third day (29 June).
