Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 166 Issued at 2200Z on 14 Jun 2012
IA. Analysis of Solar Active Regions and Activity from 13/2100Z
to 14/2100Z: Solar activity was moderate. Region 1504 (S16E01)
produced a long duration M1/1n flare with maximum at 14/1435Z. This
event was associated with a 1400 sfu Tenflare and a Type IV radio
sweep. This region showed growth and maintained its
beta-gamma-delta magnetic configuration. An associated CME was
observed in STEREO imagery at 14/1424Z with an estimated
plane-of-sky velocity between 900 and 1100 km/s.
IB. Solar Activity Forecast: Solar activity is expected to be
moderate. An isolated M-class event is likely from Region 1504.
IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: Geomagnetic activity is
expected to be quiet on 15-16 June. An increase to unsettled to
active levels is expected early on day 3 (17 June) due to combined
effects from both the 13 June and 14 June CMEs.
