Hey guys!! I’m pretty sure the majority of you are from mainland America so you don’t have the opportunity to see the northern lights, like, ever. Tonight you can!! Possibly. There’s a pretty severe geomagnetic storm going on and it’ll be hitting pretty darn south and a whole crap ton of people that have never seen northern lights, might be able to see them!!

I highly encourage everyone in the red/yellow lines to try to take a look tonight! I grew up with northern lights literally in my backyard and they’re just such a pleasant sight to see. According to the weather network it’ll go down as far as Alabama!

everyone in the northern hemisphere say "thank you" to Earth's magnetic field for protecting us from the big beautiful eldritch horror in the sky
