The northern lights became visible when the sky darkened enough to see them. The crisp shape of the arc of the northern lights emerging from the remains of day light in the dusk sky. Again they crept south getting higher in our landscape view as the evening progressed. We got 3 bright bursts of activity and the best and brightest was right at the end of our trip. Finally we got that memory moment to think back to from the night, tall shafts of light wandering around the sky. What a sight!
