Aurora Borealis over Okobojo Creek embayment of Lake Oahe
September 29, 2016

The forecast of possible auroras on Space Weather.com led me to find a site where I could see the north over water.
 I hoped for a site with no anthropogenic lights, but that seems impossible to find.
 In the end, I liked how the arc of the aurora framed the lights.

I waited until around 11:00 PM until this started to show up in the north.
The bowl of the Big Dipper is on the left hand side.

Approximately 11:30 PM, it started to get active.

All I can say is wow! One of the brightest and most active displays I've seen in South Dakota.
It stayed fairly low on the horizon.

The green colors I could see, the camera collected the red too.
This is shortly after midnight.

The height of the display. The waves of lights moving
across the sky was really something to see.

Aurora further to the northwest with the Big Dipper.
