Aurora time lapse

It's not great quality, but here's a short time-lapse I made last night when the aurora was out. It was a nice little show, not fantastic, but nice. It was kind of cool because it was partly cloudy and the clouds were moving too. This view is from our driveway.

Blue, white, and yellow

After 2.5 days of working on Classical Mechanics homework, then half a day of grading, Jason made me go out and take pictures of things. It was really a nice day, and its been almost three since I've really gone outside, so it was nice. The weather has been getting chilly here. We had our second serious frost this morning and I think we are seeing the last of the autumn leaves. It's good to take a break.

New climbing wall
Here's the new climbing wall on campus. It's outside. I guess it will be an ice climbing wall in the winter.

Last of the leavesThere's still a bit of gorgeous foliage on the trees.

Fairbanks Shakespeare TheatreThe Fairbanks Shakespeare Theatre should be winding down now since the snow will be here soon. The building in the background is where I work.

Fingers crossed

Let's have a clear night tonight! From spaceweather.com:
GEOMAGNETIC STORM: A strong-to-severe geomagnetic storm is in progress following the impact of a coronal mass ejection (CME) at approximately 12:15 UT on Sept. 26th. The Goddard Space Weather Lab reports a "strong compression of Earth's magnetosphere. Simulations indicate that solar wind plasma [has penetrated] close to geosynchronous orbit starting at 13:00UT." Geosynchronous satellites could therefore be directly exposed to solar wind plasma and magnetic fields. High-latitude sky watchers should be alert for Northern and Southern Lights after nightfall. Aurora alerts: text, voice.

Planetary K-index
Now: Kp= 8 severe
24-hr max: Kp= 8 severe

(The K-index is out of 9)

Sadly we may not get to see much in Fairbanks, but the lower 48 should get a show. Typically when the K index is real high we get more diffuse aurora and only short bursts of the good stuff. We'll see what happens!

*****Update*****

Here's the latest statistical map from the University of Alaska, Fairbanks. The more in the darker the green band you are, the better chance you have to see it. So northern U.S. watch out!

Ode to Aurora

Yesterday was exciting because NPR did an equinox post on their picture show and used some of my aurora photos. Here's a link to the post:
NPR: Auroras on Autumnal Equinox

The title is a little misleading since two of the three photos were from the August 29th storm and one was from earlier this month, not really on the equinox. It's a fun post anyway. Here's a bunch more photos I've taken in Fairbanks:

Also, this video from the International Space Station has been making its way around the internet, but if you haven't seen it yet you need to. If you have seen it, you should probably watch it again.

This gorgeous view of the aurora was taken from the International Space Station as it crossed over the southern Indian Ocean on September 17, 2011. The time-laps made from still images spans the time period from 12:22 to 12:45 PM ET.

While aurora are often seen near the poles, this aurora appeared at lower latitudes due to a geomagnetic storm – the insertion of energy into Earth's magnetic environment called the magnetosphere – caused by a coronal mass ejection from the sun that erupted on September 14. The storm was a moderate one, rated with what's called a KP index of 6 on a scale that goes from 0 to 9, caused by just a glancing blow from the CME. As particles from the incoming CME moved into the magnetosphere they traveled around to the back side -- or night side, since it is on the opposite side from the sun -- of Earth and then funneled down onto Earth's poles and even lower. As the particles bombarded oxygen and nitrogen in the atmosphere, the atoms released a photon of light that we see as the beautiful colors of the aurora.

Equinox

Almost gone
The leaves around the house are almost totally gone!

It is here again, the autumnal equinox. The equinox officially occurs on September 23 at 9:04 am UTC. As it passes us by, normal length days begin to fade away as well. Nobody can stop it from happening. For us this means that winter will be here within weeks. It is a solemn occasion since summer is so brief here, but there is a hidden excitement for winter too. Fairbanks is pretty when it is covered in snow and the aurora shows up almost every clear night. Also, skiing and snowshoeing can happen. Many more areas become accessible by foot in the winter months . . . because Alaska is a giant swamp.
Smith Lake
I took a walk to Smith Lake yesterday with some friends. It was pretty nice, but I left with sopping wet shoes.

Our autumn really ends around the first or second week of autumn if you define the winter as beginning once snow is on the ground. We once again had temperatures above average for late summer which has been really nice. The forecast for the week is telling us to get ready though; one more day in the sixties, a few days of fifties then the highs are in the forties. I'll bet we won't see 60°F again until April or May. Snow showers are already in the forecast in the coming days. It won't stick at all, but things are going to start freezing.

Oops, we went to Denali again

It's getting harder to stay away because the park is so incredibly awesome. Of course, September is here which means its full on fall foliage season for most of the interior of Alaska. Some places we've been to are already past peak. Luckily the park encompasses a lot of different climate zones, so you don't have to go far to find the fall colors.

It's autumn again
Alaska is pretty
These shots are from the start of the Park Road near the park entrance. The valleys are filled with yellow and orange.


We drove into the park to the Savage River, stopping a few times along the way once the landscape became red.

Panorama

A walk (and a nap) along the Savage river proved to be a relaxing way to spend the early afternoon. The river is gorgeous, the walking is easy, and the landscape is breathtaking. I could easily just take my time and just walk forever here.

I also took a walk up the Rock Trail and the Alpine trail, also in the Savage River area. A little higher up the foliage was at peak again. Pretty, pretty, pretty.
Colors!

Bull moose likes the fall foliage
The only wildlife I saw were two moose. I was way too far away to get any good shots of this big guy, but he makes a pretty good dot in the yellow and red textures.


Of course, I took a lot of pictures and don't have the time to post all of them now, but I will post updates over the next few days. Classwork and teaching are starting to take over again and soon winter will be here. At least it's aurora season!

Stovetop

Stovetop
Stovetop, a photo by Lee Petersen on Flickr.

This is the stove inside the home of Fannie Quigley in Kantishna, Alaska, a town encompassed by Denali National Park. A good glimpse into her life can be read in her Blueberry Pie recipe:

"First, in early August pick five gallons of blueberries as they ripen on the hillside in back of your mining claim. 
Before the creeks run dry in the summer, pan some gold out of your claim.

Then, in early fall shoot a good fat bear. Skin the bear, and butcher it. Haul it, one quarter at a time, in your backpack to your cabin.

When the first snows come to the hills, hitch up the dogs and mush fifteen miles down the valley for firewood. Haul ten or fifteen cords to keep the woodstove going in the cabin for the winter.

Using a large iron kettle and the wood you've hauled, render the bear fat into lard.

Hitch up the dogs again and mush 125 miles to Nenana. Trade some of your gold dust for 100 pounds of flour and 50 pounds of sugar. Load it onto your sled and mush home. Be sure to avoid the overflow on the Toklat River so the flour doesn't get wet.

Use the bear fat lard and the flour to bake a dozen flaky pie crusts in the oven of your wood cookstove. Keep the stove stoked with good dry wood to maintain a high temperature.

Mix the blueberries with some sugar, and add enough flour to bind up the juices. Put the filling into the crusts and bake. Don't let the fire in the stove get too hot, or the pies will burn.

Cool the pies, then store them frozen in the permafrost mining tunnel behind the cabin.

When company comes, go out and get a pie out of the tunnel. It will taste as good as fresh and astonish your guests."


I went back to post this after reading an article in the newsminer about an Alaskan woman who punched a bear in the face when it tried to take her dog. Alaskan women are tough.
