Straight Up Awesome
It's quite common to see clouds at night illuminated from below by light pollution. But it's strange seeing clouds turn green, illuminated from above. This was the solar wind stream I traveled to Alaska to see, and it arrived about 24 hours after I did at 2AM. The aurora was mesmerizing to watch as it became very bright, and twisted and pulsed and flickered. It's not often that I point my camera straight up.
