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 161 Issued at 2200Z on 10 Jun 2014IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a X2 event observed at
10/1142Z from Region 2087 (S18E71). There are currently 7 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, two, and three (11 Jun, 12
Jun, 13 Jun).
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 477 km/s at
10/1947Z. Total IMF reached 9 nT at 10/1144Z. The maximum southward
component of Bz reached -6 nT at 10/1203Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one and two (11 Jun, 12 Jun) and quiet to
active levels on day three (13 Jun). Protons have a chance of crossing
threshold on days one, two, and three (11 Jun, 12 Jun, 13 Jun).
