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 196 Issued at 2200Z on 15 Jul 2014IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
15/0305Z from Region 2109 (S08, L=221). There are currently 2 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (16 Jul,
17 Jul, 18 Jul).
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
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 525 km/s at
15/1126Z. Total IMF reached 15 nT at 14/2100Z. The maximum southward
component of Bz reached -9 nT at 15/0547Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (16 Jul, 17 Jul)
and quiet levels on day three (18 Jul).
