Photographing the Aurora Borealis

September 18, 2013  •  2 Comments


One of the highlights of my recent trip to Alaska was the chance to view the aurora borealis, or northern lights.  I had seen them only once before and many years ago when a very unusual level of solar activity created a display that was seen as far south as Connecticut.

The aurora are normally visible only in far north or south latitudes — 10 to 20° from the magnetic pole. The lights are caused by charged particles colliding with atoms in the Earth’s atmosphere. A solar wind is a stream of these charged particles which originate in the upper atmosphere of the sun and are attracted to the Earth’s magnetic field.

The aurora can appear as a slight glow in the sky, a curtain of light, or bright swirls of light, generally a fluorescent green. They may remain static for long periods or change shape rapidly, creating swirls of light.

Solar activity seems to peak around the times of the equinoxes, making my early-September trip an ideal time to view the lights. I was in the right place (the auroral zone passes through northern Alaska) at the right time (within two weeks of the autumn equinox).  Now all that was needed was a good aurora forecast to coincide with a clear sky.

The conditions were ideal on September 6 when our photo group was staying in Kaktovik, a small Inupiat village located around 70°N. We got some spectacular displays and there were frequent clicking sounds coming from the cameras of eight happy photographers.
