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.

C. Geomagnetic Activity Summary
The geomagnetic field was at active to major storm levels from yesterday through 10/1600 UTC. Since then conditions have been predominately unsettled. The high speed solar wind continues, but has lessened from the 750-900 km/s of yesterday to a steady 620 km/s. The greater than 2 MeV electron fluxes continue to be at high levels.

X1.1 solar flare

We have only just started to relax following the moderate G2 geomagnetic storm conditions from a massive coronal hole and suddenly... bam... our Sun surprises us all with a X1.1 solar flare (R3-strong) that came from sunspot region 4046 which is just rotating into view on the east limb.
