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.

CME arrival, G3 storm watch

A coronal mass ejection has arrived at our planet. This is the first of possibly two coronal mass ejections that were expected to arrive from filament eruptions on April 12 and 13. The minor G1 geomagnetic storm threshold has already been reached and the NOAA SWPC has a strong G3 geomagnetic storm watch in place for tomorrow, 16 April. Keep an eye on the data here on this website in the hours ahead. There is more action to come!
