AURORAS LOVE EQUINOXES

NOAA - March 2024

 

The vernal equinox is only 3 days away. That's good news, because auroras love equinoxes. Researchers call it the "Russell-McPherron effect." At this time of year, cracks form in Earth's magnetic field, allowing even weak gusts of solar wind to spark a good display. Here's an example last night from 35,000 ft:

"While flying on the Dreamliner from Calgary to Paris, I witnessed an amazing display of auroras near Rankin Inlet in Canada," reports pilot Matt Melnyk. "At times we were so far north, I could see the aurora to the south! The flight deck is the best office view in the world."
