Cue RichA to complain about light pollution:

Aurora can ruin observing.

So can the sun or the moon. Both are valid targets for observation in their own right.

Why do those who suffer from light pollution demand dark skies for deep sky viewing? That's like living on the beach in Florida and expecting local ski resorts!
