Flickering Auroras
Pulsating or flickering auroras typically follow after a major substorm. They might be caused by electrons bouncing back and forth from pole to pole. Neat to watch but tough to shoot except on video. A substorm is a usually brief outburst or brightening and increase in motion that might last only a few minutes before subsiding. And after it subsides the aurora can sometimes turn into a pulsating form. Never gets tired of seeing the northern lights. I can understand why people travel around the world to see them. After years of photographing this natural phenomenon I still find it beautiful and fascinating every time.
