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 166 Issued at 2200Z on 14 Jun 2012IA. 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.
