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 173 Issued at 2200Z on 22 Jun 2014

IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z

Solar activity has been at very low levels for the past 24 hours. There are currently 7 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be low with a slight chance for an M-class flare on days one, two, and three (23 Jun, 24 Jun, 25 Jun).
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
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 459 km/s at 21/2117Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 153 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to minor storm levels on day one (23 Jun) and quiet to active levels on days two and three (24 Jun, 25 Jun) in response to a series of transient passages.
