How To See the Northern Lights
The SWPC's forecast has the G1 alert in effect from 8pm to 2am EST Tuesday into Wednesday morning. Wherever you are, you won't see anything while the sun is still up. So, your best bet for quality viewing is to get out a bit after sundown.
For the best experience, get away from the light pollution in cities. That will impair your ability to see any display that's there. Additionally, an SWPC representative previously told Thrillist, "You need very clear skies, a good view of the northern horizon (no trees, buildings, or hills), and it needs to be dark." For viewers in the US, the northern lights are most likely to sit along the northern horizon rather than directly overhead.
The key to crossing the display off your bucket list is persistence and patience. If the aurora isn't there, there's nothing that says it won't be in a couple of minutes. If it's there right now, it could be gone in a flash. You really have to stick with it.
The aurora is occasionally visible in the northern US. This isn't unprecedented, but it's absolutely worth getting out there if the conditions are right and there's no cloud cover in your area. If it appears, you will not regret bundling up and enjoying the show.
