F4fud and everyone else!
Yes you could see it over GOT, in fact just a couple a weeks ago, i saw a really spectacular Northern lights over GOT, one of the best i ever seen. And i have been doing nightfligts in northern Scandinavia 64-66N for several years and seen them quite often.
They can be shaped very differently and in many colors but the most common i have seen is white /green and a little purple sometimes red maybe and shaped like hanging drapes (both up and down) constantly changing form!
