A couple of comments/questions: I live in Tromsoe during the school year and northern Minnesota during the summers. We routinely see northern lights both places. No surprise in Tromsoe, of course, but Minnesota doesn't fulfill either the latitude or season requirements. Also, the northern lights in these places are very different. In Tromsoe they're usually green and "vertical", so to say, but in Minnesota they tend to be lots of colors, and more spread out through the sky, or if they are a sort of stream there, then they often cover a greater portion of the sky. And, as for the diffuse one's not being so interesting.... well, spend a few weeks in the dark and I bet they'll be quite welcome! Curt Rice
