Photographer's Note

this is a shot of bands moving like curtains across the sky, the operative words is moving- the constant movement makes it a bit tricky with long exposures.
The different forms of aurora are as follows:
arc: an evenly curned light with a smooth lower edge that may extend from horizon to horizon
band: similar to arc. They can be described as 'quiet', 'active', 'streaming'(sudden increase in brigthness), or 'flaming' (sudden bursts at the bottom- flaring up to the top).
corona: rayed arcs of bands seen from underneath, so the light seems to beam out like a sunburst
patch: small cloudlike area
ray: thin beam or shaft of light
veil: large featureless expanse of light
