Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 175 Issued at 2200Z on 23 Jun 2012
IA. Analysis of Solar Active Regions and Activity from 22/2100Z
to 23/2100Z: Solar activity was low. A long-duration C2 X-ray flare
occurred at 0750Z originating from past the west limb. A CME was
associated with the flare but is not expected to be geoeffective.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low.
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z:
Geomagnetic field activity was at mostly quiet levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
during the period.
IIB. Geophysical Activity Forecast: Geomagnetic activity is
expected to be mostly quiet during the period (24 -26 June).
