Viewing the Aurora in the Northern Summer

During the northern summer, sunlight prevents viewing the aurora at high northern latitudes. As the sun climbs in the sky until June 21st and then descends, the nights are too light to see the aurora. Because the magnetic pole is displaced toward North America, the auroral zone shown on our maps is at low enough latitudes to be seen even in the summer. Here are the rules of thumb for auroral viewing based on your latitude.

 

North of 70°

North of 70  Latitude, aurora viewing very limited April15 through August 25.

 

North of 65°

North of 65° latitude, aurora viewing very limited May 1 through August 10. The auroral index should be 2 or more to see it south of this latitude.

 

North of 60°

North of 60° latitude, aurora viewing very limited May 15 through August 1. The auroral index should be 3 or more to see it south of this latitude.

 

North of 55°

North of 55° latitude, aurora viewing very limited June 10 through July 1. The auroral index should be 4 or more to see it south of this latitude.

 

South of 55°

South of 55 degrees latitude, the aurora should be visible to observers in Canada and the northern US all summer if the auroral index is 4 or more.
