August Aurora Activity on The Kenai

Oh what a month it has been! The Aurora Borealis (otherwise known as the Northern Lights) have been out in full swing and dancing the nights away in the Alaska’s Playground sky.

Because it’s been such a bright and magical month on The Kenai, Alaska’s Playground, we decided to grab a collection of some of our favorite photos for all of our friends to experience along with us.

These photos have been taken by amateur photographers and experienced photographers alike. We have gathered most of this incredible photo content from our Facebook page as well as some other great pages including our friends at Alaska Magazine, Aurora Lovers, The Milepost, and many more. And we are also excited to share some really cool facts about Northern Lights from Live Science.

Aurora displays are created when protons and electrons stream out from the solar surface and slam into the Earth’s magnetic field. Since the particles are charged they move in spirals along the magnetic field lines, the protons in one direction and the electrons in the other. Those particles in turn hit the atmosphere. Since they follow the magnetic field lines, most of them enter the atmospheric gases in a ring around the magnetic poles, where the magnetic field lines come together.

The air is made up largely of nitrogen and oxygen atoms, with oxygen becoming a bigger component at the altitudes auroras happen – starting about 60 miles up and going all the way up to 600 miles. When the charged particles hit them, they gain energy. Eventually they relax, giving up the energy and releasing photons of specific wavelengths. Oxygen atoms emit green and sometimes red light, while nitrogen is more orange or red.

Satellites can take pictures of the aurora from Earth’s orbit — and the images they get are pretty striking. In fact, auroras are bright enough that they show up strongly on the nightside of the Earth even if one were looking at them from another planet.

Occasionally the auroras are visible farther from the poles than usual. In times of high solar activity, the southern limit for seeing auroras can go as far south as Oklahoma and Atlanta — as it did in October 2011. A record was probably set at the Battle of Fredericksburg in Virginia in 1862, during the Civil War, when the northern lights appeared. Many soldiers noted it in their diaries.

The northern lights look like fire, but they wouldn’t feel like one. Even though the temperature of the upper atmosphere can reach thousands of degrees Fahrenheit, the heat is based on the average speed of the molecules. After all, that’s what temperature is. But feeling heat is another matter – the density of the air is so low at 60 miles (96 kilometers) up that a thermometer would register temperatures far below zero where aurora displays occur.

Auroras are relatively dim, and the redder light is often at the limit of what human retinas can pick up. Cameras, though, are often more sensitive, and with a long-exposure setting and a clear dark sky you can pick up some spectacular shots.

One very important thing for our visitors to remember; you can’t ever predict a show! One of the most difficult problems in solar physics is knowing the shape of a magnetic field in a coronal mass ejection (CME), which is basically a huge blob of charged particles ejected from the sun. Such CMEs have their own magnetic fields. The problem is, it is nigh impossible to tell in what direction the CME field is pointing until it hits. A hit creates either a spectacular magnetic storm and dazzling aurora with it, or a fizzle. Currently there’s no way to know ahead of time.

NOAA has an online map that can tell you what auroral activity looks likeon any given day, showing the extent of the “auroral oval” and where one is more likely to catch the lights.

It truly is so special to see these magical lights appearing in the middle of town, in the middle of the night, near some of our favorite local shops. Like this photo below at Veronica’s Cafe in the town of Kenai.

Have you ever seen the Northern Lights? If not, be on the lookout! And if you capture your memories, be sure to share them with us HERE! Happy Friday, friends!
