Geophysical 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.

X4.0 solar flare

A X4.0 (R3-strong) solar flare peaked at 08:30 UTC this morning. It was of course departing sunspot region 4274 which has been the source of so many solar flares and even geomagnetic storms this past week that provided the fireworks.
