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 126 Issued at 2200Z on 06 May 2014

IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z

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 06/0903Z from Region 2051 (S09W92). There are currently 9 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on day one (07 May) and expected to be low with a chance for M-class flares on days two and three (08 May, 09 May).
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
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 425 km/s at 05/2150Z. Total IMF reached 5 nT at 05/2209Z. The maximum southward component of Bz reached -3 nT at 05/2139Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on day one (07 May) and quiet to unsettled levels on days two and three (08 May, 09 May).
