We're currently in a period of solar maximum, which is good news for aurora borealis enthusiasts .

The sun operates on a roughly 11-year cycle of magnetic activity, says Ian Mann , a space physicist in the University of Alberta's Faculty of Science .

During periods of solar max , these zones tend to expand closer towards the equator, moving into areas where more people live.

Some of the purple or red colors can be difficult to see with the human eye.

Cameras are much more sensitive and able to pick out those wavelengths of light.

Sometimes you'll see nothing for a long stretch of time, "then suddenly there's a big release of this energy and the sky fills with this burst of dancing lights".
