    very true. There is a satellite being launched this month which is suppose to be the first of its kind studying NLC. There is much we dont know about. (PMC - polar mesospheric clouds which are sometimes called NLC as named by ground observers)

    By the way, they are a mesopause phenomena [~90km].
