Geophysical report

Previous rotation Previous day Calendar
Next day Next rotation
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.

B. Proton Events
A greater than 10 MeV proton event began today at 1750 UTC and is still currently in progress. The event appears to have originated from today's behind-the-limb event.
C. Geomagnetic Activity Summary
The geomagnetic field was unsettled to slightly active. Solar wind observations suggest that the activity originated from enhanced density and interplanetary magnetic fields during a solar sector boundary crossing.

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.
