Nearly an hour after midnight, an auroral substorm erupted, filling the skies above with the gossamer curtains of green light. Photographed March 2018.
As the substorm spread across the sky, arcs to the west of us soon erupted. Photographed March 2018.
Near the end of the three-hour spectacle, my wife and I waved a thank you to the beautiful auroral display we'd seen. Photographed March 2018.
