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 190 Issued at 2200Z on 09 Jul 2014IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z 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
09/0026Z from Region 2113 (N09E35). There are currently 9 numbered
sunspot regions on the disk. No earthward directed coronal mass
ejections were observed during the period.
IB. Solar Activity Forecast
Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(10 Jul, 11 Jul, 12 Jul).
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
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 386 km/s at
09/1824Z. Total IMF reached 7 nT at 09/1616Z. The maximum southward
component of Bz reached -6 nT at 08/2115Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (10 Jul, 11 Jul, 12
Jul). Protons have a slight chance of crossing threshold on days one,
two, and three (10 Jul, 11 Jul, 12 Jul).
