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 154 Issued at 2200Z on 03 Jun 2014

IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z

Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was an M1 event observed at 03/0409Z from Region 2077 (S08E17). There are currently 5 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 (04 Jun, 05 Jun, 06 Jun).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 380 km/s at 03/1702Z. Total IMF reached 10 nT at 03/1824Z. The maximum southward component of Bz reached -8 nT at 02/2233Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (04 Jun, 06 Jun) and quiet levels on day two (05 Jun).
