The great all-sky aurora display of March 6, 2016 over the Churchilll Northern Studies Centre, Churchill, Manitoba, in a view looking north. Here, the curtains have the characteristic green and red tint and converge to the zenith, with red dominating the sky at this point. This is one frame from a time-lapse sequence shot with the Sigma 8mm fish-eye lens and Canon 6D, intended for projection in digital planetarium theatres.
