Weather, twilight, and auroral observing from Spitsbergen in the polar winter
ABSTRACT Despite the harshness of the weather, the winter months on Spitsbergen provide good opportunities for auroral observing. December is usually the cloudiest month, but it also has many short-lived periods of post-cyclonic clearing of excellent clarity. January, however, is the most favourable...
