The Aurora season is under way up in Yellowknife, Northwest Territories. Photographer Valerie Pond is always on the hunt for the perfect photo.

She says when she got off work at 11 p.m. Friday, the Northern Lights were just starting to dance in the sky over the city.

Pond and her son drove out to Prosperous Lake, 25 miles outside of the city.

We arrived to find several Japanese tourists along the lake shore laughing, giggling and so excited to see the Aurora in the night sky, she said. It is always a joy to be around people that have never experienced the beauty of the Aurora as it reminds me just how very lucky we are to see them almost nightly.

She says a manager at one of the local hotels told her bookings are up 60 percent and they expect to have a very busy Aurora season.

According to the Geophysical Institute at the University of Alaska Fairbanks, the aurora is a luminous glow of the upper atmosphere, caused by energetic particles that enter the atmosphere from above.

The composition and density of the atmosphere and the altitude of the aurora determine the possible light emissions. The colors that we see are a mixture of all the auroral emissions. Just like the white sunlight is a mixture of the colors of the rainbow, the aurora is a mixture of colors. The overall impression is a greenish-whitish glow. Very intense aurora gets a purple edge at the bottom.
