Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 165 Issued at 2200Z on 13 Jun 2012IA. 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.
