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 183 Issued at 2200Z on 02 Jul 2013

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C7 event observed at 02/1749Z from Region 1785 (S11E62). 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 and two (03 Jul, 04 Jul) and expected to be very low with a chance for a C-class flares on day three (05 Jul).
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
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 498 km/s at 01/2136Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 4429 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on day one (03 Jul), quiet to unsettled levels on day two (04 Jul) and quiet to active levels on day three (05 Jul).
