Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 165 Issued at 2200Z on 13 Jun 2012
IA. Analysis of Solar Active Regions and Activity from 12/2100Z
to 13/2100Z: Solar activity was moderate. Region 1504 (S17E14)
produced a long duration M1/1n flare at 13/1317Z associated with a
260 sfu Tenflare and a Type IV radio sweep. This region showed
growth in the leading spots and developed a beta-gamma-delta
magnetic configuration. An associated CME was observed in LASCO C2
imagery at 13/1412Z with an estimated plane-of-sky velocity between
700 and 800 km/s. Old Region 1507 was split into two regions as it
showed two distinct bipolar areas and now consists of Region 1507
(S25W13) and Region 1508 (S28W06).
IB. Solar Activity Forecast: Solar activity is expected to be low
to moderate. An isolated M-class event is likely from Region 1504.
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: Geomagnetic activity is
expected to be quiet on 14-15 June. An increase to unsettled levels
is expected mid-day on day 3 (16 June) due to a possible glancing
blow from todays CME.
