NOAA has issued a severe geomagnetic storm watch for this weekend. The space weather forecast is for auroras to be visible potentially all the way down to California. North of 45 degrees should be an absolutely amazing show.
If you're flying from the US to Europe (or the other way around) at night, sitting on the northward-facing side of the plane might offer you a great view. And travelers to the Nordic countries will almost assuredly get an amazing show. Even Scotland might get a peek.
Keep your eyes open tonight through Sunday night -- you might see a historic display!
You can track the the aurora at this site: Space Weather
Also, if you still have your solar eclipse glass, you can use them to see the absolutely massive sunspot that's producing the storm. DO NOT LOOK DIRECTLY AT THE SUN WITHOUT ECLIPSE GLASSES!
Hope if the aurora is on your bucket list, this is your weekend to bag it!
