Rare has conditions with it. The best time to see them in this area is in the late autumn, but the late autumn is almost always cloudy and wet. So having them and getting to see them are tow different things. Up north about 800km (500mi) in lappland it gets much colder earlier, so the skies are clear and tgeybare very bright. I have only seen them there on one trip, but they were amazing. I had no proper camera with me back then and phones didn't have cameras in them yet :D
It is that "awe-inspiring" feeling I love about them.
