“The sky is dancing!” wrote my friend. I threw on a warmer coat and headed back outside. Pillars, curtains, and swirls of light danced along the horizon. My jaw dropped as the pillars shot upward, and then overhead and behind me. Light danced across even the southern sky. And directly above me, the curtains turned to curving bands that flashed, wiggled, and swirled. After almost losing my balance, I gave in and lay down on the snow to look straight up.
