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 14 Jun 2014IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
14/1929Z from the east limb. There was a Type II radio sweep (est 396
km/s) with the flare and a CME was later observed on emerging from the
east limb. There are currently 9 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate
with a chance for X-class flares on days one and two (15 Jun, 16 Jun)
and expected to be low with a chance for M-class flares and a slight
chance for an X-class flare on day three (17 Jun).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
425 km/s at 14/1344Z. Total IMF reached 7 nT at 14/0000Z. The maximum
southward component of Bz reached -6 nT at 14/0016Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 113 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on days one and two (15 Jun, 16 Jun) and
quiet to unsettled levels on day three (17 Jun). Protons have a chance
of crossing threshold on day one (15 Jun), have a chance of crossing
threshold on day two (16 Jun) and have a slight chance of crossing
threshold on day three (17 Jun).
