Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 226 Issued at 2200Z on 13 Aug 2012
IA. Analysis of Solar Active Regions and Activity from 12/2100Z
to 13/2100Z: Solar activity was low. Region 1543 (N20W05) produced
the largest event of the period, a C2 flare at 13/1240Z, with
associated Type II (estimated velocity of 736 km/s) and Type IV
radio sweeps. Analysis is underway to determine the potential
geoeffectiveness of a possible CME associated with this flare as
more data becomes available. Region 1543 also produced a C1/Sf at
13/0413Z, with an associated Type IV radio sweep. Regions 1543 and
1542 (S12W18) were generally unchanged and have beta-gamma magnetic
configuration.
IB. Solar Activity Forecast: Solar activity is expected to be low
with a slight chance for an isolated M-class flare.
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z:
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled with a slight chance for an active
period on day 1 (14 August) due to a high speed stream from a
coronal hole. Days 2 and 3 (15 - 16 August) are expected to be at
predominately quiet levels.
