Wow, it looks impressive. It's really beautiful and I think it's the first time I've ever seen a red aurora borealis. I had always seen it in green. From photos obviously, from the Caribbean I don't have the joy of being able to see one in person. Hopefully the day will come when I can be in the presence of one and be able to take pictures of it.
Great job and thank goodness you had the patience to wait those extra minutes to get those tremendous results.
Well, with extreme phenomena that only happen every few or even decades, there might be a chance of seeing the aurora even in the Caribbean! In the 21st century, there were maybe 2-3 such events. As for the colors, the further from the Arctic Circle, the more they behave. It all depends on the aurora's strength. In weak conditions, only the green aurora, visible in the polar zone, is produced. In stronger phenomena, it takes on various colors: red, purple, green, pink, and even blue! In Poland, where I live, pink/purple is the most common.
Best regards!
