The (nearly) Eternal Golden Hour

You are sitting on a warm, tropical, beach drinking a margarita. As you watch the day wane away the sun dips lower on the ocean horizon, and the landscape transforms into brilliant oranges and purples. Behind you the palm trees are bathed in orange, and the landscape has taken on incredible colors with accentuated shadows of even the shortest plant or sandcastle.  Almost certainly you bring out your cell phone or camera, because, like all photographers, you find the beauty of the Golden Hour to be irresistible, and you know the peak experience will be short lived.  Perhaps you even think to yourself that you wish the beauty of that light could last forever. What if it could?

The Golden Hour is also called the “magic hour” and for a landscape photographer there is no better time to be outside. The terms refer to the period of time when the sun is 6 degrees or less from the horizon. In many regions, like the balmy beach scene above, the moment as the sun sweeps through that 6 degree sweet-spot is relatively short. However, in Polar regions like Alaska, the winter sun has such as a low, southern trajectory, that the sunset-like colors almost never fade.

This diagram demonstrates the concept of solar angle, which, as I found out, stays at <= 6 degrees for a full three months in Fairbanks, Alaska. http://www.esrl.noaa.gov/gmd/grad/solcalc/azelzen.gif

There are a variety of tools, apps, and websites to calculate the solar angle at your location.  I used the NOAA ESRL Sun Position Calculator to determine that in Fairbanks the sun dips to the 6 degree mark on October 24th, 2015 and will remain below 6 degrees until February 26th, 2016. To illustrate the effect of the polar magic hour the images below showcase the colors, and shadows achieved by the low-lying sun. For 3 months, the silver lining of our short, winter days is a luxurious landscape lit by an eternal Golden Hour.

Leonid Meteors, Aurora Borealis, Angel Rocks, Alaska!

We shut the truck off and stepped out into a cool night and a light breeze which shocked the face. My friend Ross and I were after auroras, and we planned to summit Angel Rocks in the Chena Recreation Area to spend the night and watch it. The sun was low in the sky as we started up the 1.6 miles to the summit of Angel Rocks. By the time we had reached the top of the ~1000 foot climb, the breeze funneling up the canyon below had stopped, and the sun melted into the horizon leaving a blue and gold light which lingered for hours. With short days in Fairbanks, it was hard to forget it was only about 5:30! There was a lot of night to go.

I was delighted to find a cave at the top of Angel Rocks. It was two ended and had large crevasses in the ceiling to view the stars. In the middle I could stand all the way up, and the larger south facing entrance was almost 8 feet tall. I’m just speculating, but I think this cave was formed as a magma bubble. The geology of the summit was far different than any geology I had seen in the Fairbanks region. In contrast to the normal scree slopes and shale of the region, the exposed rocks were granite and had forms which suggested bubbling magma. The rock outcrop where we stood was very unique!

The cave at the top of angel rocks was amazing! The double entrance was passable and you could easily stand up inside. Here is a picture from out of the cave looking south. You can just see the tail of the milky way.

The Leonids

In a collision of natural phenomenons, the Leonid meteor shower lined up with an incredible aurora display. Each year the Leonid meteor shower peaks around the 17th or 18th of November. Named after Leo, the constellation that they seem to radiate from. The Leonids Meteor Shower is actually small pieces of the comet Tempel-Tuttle which burn up as they enter our atmosphere.  Incredibly, the size of the majority of particles range from grains of sand to pea-size.The largest meteors are often only marble sized pieces of comet. That’s a lot of light from a particle the size of your favorite shooter!! These particles burn up because the air in front of them is compressed and heated which scorches the meteor. That’s way different than I was ever taught (i.e. they burn up because of friction with the air). How fast do they have to be moving to build up that air pressure? The particles can enter the upper atmosphere at 160,000 mph! The Leonids were 24 hours from peak activity, and throughout the night they dazzled us with frequent and long tails.

The Aurora

As the sun set the aurora immediately started up. In fact, with an ‘official’ start time of 5:30 PM it was the earliest I have ever seen the aurora appear! It certainly seemed to be a good omen for the night to come.

The aurora had already 'booted up' as the sun set. That's an incredible show of energy!!

Over the course of the night we enjoyed three bursts of incredible aurora. From 5:30 – 7:00 PM, 9:30 – 11:30 PM and from 5:30 – 6:30 AM. Although sleeping in the cave would have been VERY awesome, the night was so warm that I was content to roll out my sleeping bag under the stars and slumber around midnight. I awoke at 5:30 AM not minutes before an incredible corona dominated the overhead skies (captured in timelapse!). I think my aurora sense was tingling and telling me to wake up!

This capture of the aurora over Angel Rocks, Alaska pretty much says it all. The lone spruce, rock outcrop and rich aurora all make for an amazing shot!

For the second night in a row the aurora put on an unforgettable show. I think the aurora are like fingerprints. They may look alike, but none are ever the same! For its immense status in the sky, I had never seen aurora that stayed as intense as this one. At times you could have read a book by it, and all through the night the sky was filled with incredible beauty and auroral ballerinas. In Minnesotan, it was “oofda good!”.
