However, it was cloudy enough to (mostly) remove the directional information needed to discern winds. Whole-sky median temperatures look good. There are very interesting temperature/brightness correlations. The chi-squared distribution had an extended high-end "tail". Perhaps this is a signature of cloud, or maybe indicative of emission from an extended height range during the aurora? MC 13-Nov-1998.
