Aurora

Aurora
A test shot from early on in the night. Notice the two meteors captured in this frame. Apparently, I also caught the end of a major meteor shower.

 

This story begins Friday night when I learned that a large coronal mass ejection (CME) sent a burst of solar radiation from the sun headed toward Earth. It was predicted to intercept our atmosphere on the evening of the 8th, producing auroral activity in the high latitudes. Given the size of this solar storm, as described by spaceweather.com, I was a bit suspicious that the auroras migh be big enough to see all the way down here in northern Idaho. So, I kept a watch looking for evidence of such activity.

On the evening of the 8th, I checked Spaceweather and confirmed that there had been some strong auroral activity, and that it had been seen earlier that morning as far south as Utah. I rushed outside and didn’t see much. I set up the camera for a test shot and picked up some faint auroral glow, but it seemed to be far in the distance and nothing worth getting excited over. I was beginning to think that I had missed the aurora and should have stayed up the night before. Throuout the evening, I would periodically go out side and take a test shot of the northern sky, and while the glow got brighter, it never reached the level that it had during previous auroras. So while I went out for the last test shot at 11:30, Erin had gone to bed. I stayed up in an attempt to finish grading exams, but ended up nodding off in the middle. I admitted defeat and around midnight, decided to quit and go to bed.

Dancing Light
Curtains of light filled the sky during the most intense flare I had seen.

 

Before turning in for the night, I stepped out to check the sky once more. I figured, it wouldn’t hurt. Of course, I wasn’t expecting to see columns of light beaming high into the night sky. The aurora had really flared up. So I grabbed my jacket and my camera and decided to drive a few miles south where there were some flat fields and a clearer view of the sky. I was mostly interested in photographing the aurora with a different foreground than the usual barn and trees outside the house. When I pulled off the road and set up the camera, I got something I wasn’t expecting at all. There were full-fledged curtains streaking from the north across the sky overhead, and they could be seen clearly with the naked eye. This was too much to bear. I quickly set up the camera and snapped the first shot. Thankfully, there was cell service where I was and I was able to call Erin and get her out of bed for this one. I also called Colleen, who promptly got in her car and headed out to our place from Moscow.

Meanwhile, I stood out in the field for a good 20 or 30 minutes marvelling at the dancing curtains while snapping away. At one point, I noticed a flash in the sky. I thought maybe someone had come out with a spotlight, but there was no other human activity to be found. It happened again, and again, and soon I noticed that the light was radiating from the north and travelling toward me in waves. The activity persisted for a good 20 minutes and then subsided. At that point, the cold was getting to me, and I decided to head home rather than wait for Erin and Colleen to come out.

End of the Show
The last harrumph before fading away for the night. It was a much more quiet flare, but still beautiful.

 

The activity had subsided for a while, but I kept an eye on the reports from spaceweather.com. We went out again a little after 1:00 to see if the activity had returned, and indeed, the band across the sky had gotten brighter with some faint pillars streaking upward. Rather than drive back out to higher ground, we went into the field behind the house to see what was happening. The aurora certainly wasn’t as big as it was earlier, but it had gotten bright green. We waited to see if it would flare up some more, but it never seemed to get any bigger. So, by 1:30, we all decided to call it a night. Erin and I finally went to bed by 2:00, and after one last look at the sky, it seemed that the glow had faded out. Maybe the activity peaked again in the early hours of the morning, but I had already seen something good. After all, I had to be up in 3 hours to get ready for work.

While the lack of sleep had taken its toll on me, it was totally worth it to witness this totally awesome spectacle of the universe. A geomagnetic storm this strong doesn’t happen very often, and when it does, I’ll be sure to be outside capturing it.

    Daffodils in the Snow

    Daffodils in the Snow, originally uploaded by Matthew Singer. I’ve heard of April showers bringing May flowers, but what do April snows bring? On Friday, I awoke to a white world with about an inch of snow covering everything. It was kind of a shock considering only a week before, there were promising signs of Spring. Of course, after the snow, the temperatures are back up and the weekend’s forecast is quite pleasant.

    August Update

    I just realized that August has come and gone and I have yet to write about anything that happened during this month. It’s not as though I haven’t done anything. In fact, I was quite busy every weekend. So, let’s see, what happened in August? It got really hot. In fact, it got so hot, that doing things became unpleasant. Nevertheless, we took Clara out to Elk River to beat the heat. At first, she didn’t like sitting in the cool water, but by the end, I got her to tolerate it. We also took Clara up to Kamiak Butte….

    Potlatch River

    Potlatch River, originally uploaded by Matthew Singer. There is a Forest Service hiking trail about 3 miles due north of our house, though it’s about 7 miles to drive there. Still, it’s close for those after-work getaways. The trail is a ~5mi. loop along the Potlatch River that takes you along the river and then up to the “rim” of the canyon. The first half mile or so is paved, but it then becomes a regular old trail through the woods. There are interpretive markers along the entire length. I have been down on the trail several times, but yesterday…

  • Merry Holidays!

    I had a good Christmas this year. It began with a week of continuous snow fall. We’d have 3-6 inches here and there with warm days compacting the wet and heavy accumulation. But all of that still adds up so that by the time Christmas rolled around, the snow was over a foot deep in parts of our yard. Meanwhile the mountains have been getting hammered. Moscow Mountain has over 40 inches in the upper elevations, Brundage has over 90 inches at the summit, and I’m not sure of the current depths at Freezeout and Lolo Pass as the snotels…

    Kamiak Butte

    The Palouse, originally uploaded by Matthew Singer. The Palouse is made up of rolling hills covered in wheat and barley fields. This area was historically a prairie, so there were few trees to begin with. A few of these hills rise up well above the rest, remnants of a time when the region was more active volcanically. Kamiak Butte is one such high point, located less than 10 miles north of Pullman. The north slope is covered by a lush and beautiful forest, protected as a county park for all to enjoy. The park offers a picnic area, a campground,…

  • Winter Arrives

    So, today, Erin and I drove into Moscow to look at our snow removal options, but that ended up a fail since we left late and she had to get to work. So, I returned home with nothing new. The roads around here are plowed much differently than I expected. In Pennsylvania, the roads would be plowed down to the asphalt. Here, you’re driving on a layer of compact snow with gravel for traction. It wasn’t hard to drive on, but I was expecting to see some black instead of all white. Maybe the road will show itself over time….
