Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 234 Issued at 2200Z on 21 Aug 2012
IA. Analysis of Solar Active Regions and Activity from 20/2100Z
to 21/2100Z: Solar activity was very low. A few low level B-class
flares were observed. Three new regions were numbered: Region 1550
(S11W81) a Bxo-beta type group; Region 1551 (N13W14) a Bxo-beta type
group; and Region 1552 (S18E54) an Hsx-alpha type group. The
remaining numbered regions were stable and quiet. Several CMEs were
observed however none appear to be Earth-directed.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low for the next three days (22-24 August).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be predominately quiet for days 1-3 (22-24 August).
