Back in a Winter Wonderland

It has been awhile since you’ve heard from me, but all of that is about to change as I get my blog’n legs back under me. Until now I have been prioritizing my thesis which has now been defended. There will be several upcoming articles on the results of my work. I see no use in writing it if noone is reading it! I deem the upcoming articles as science communication”, and I hope you will find them informative.

I want to give you an update on the calendars too. Thanks SO MUCH to those who have purchased one. The response and feedback to them has been tremendous. I am now on my second and last printing. If you have been considering ordering one, now is the time! Visit: http://ianajohnson.com/customproducts/index.php/product/2016-alaskan-calendar/

Now onto the meat of this entry. Yesterday was my first day back in Fairbanks after being away for over 10 days. When I left, the remnants of a huge September snowstorm (17″) still lingered on the ground in low, shaded areas, but for the most part the ground was barren. It is amazing how only 10 days can change that. We now have 16″ of pure powder on the ground which is maintained by cold nights. Yesterday morning when I awoke it was -15F with a promise from forecasters that those temperatures will continue through at least this week. A seasonally late sunrise began at 9:15, and by noon the low light illuminated the tree tops and extenuated the shadows. I nearly skipped with joy into the  spruce bog behind my house where snow hung on the trees. I passed under trees that with a touch would have doused me in snow, and found pure joy in the beauty of this winter wonderland.

Later that night the landscape of refracting light and black spruce shadows transitioned to twinkling stars shining through a moonless night. I retraced my steps from only a few hours earlier and watched as the aurora built to the north. I watched for awhile and smiled outwardly at my knowledge of the stark contrast in light from just hours earlier.

Refracted Highlight
The sun highlights the top of a snow-pillow smothering an arched black spruce.
DSC_3248
The dynamic light of the landscape is what makes it so beautiful. Shadows of the low sun contrast heavily against lighted spires.
Black and White Winter Wonderland
I really like how the black and white contrast of needles, snow, sky lend themselves to back-and-white photography.
Winter Sun Burst
The sun erupts through a gap in the trees, but has no heat this time of year.
Arched Spruces
The large snow-load has bent many of the black spruces over. They will rebound in the spring once their burden has been lifted.
Snow Covered Aurora
At night, the aurora lit up the landscape where I watched the the sun play across the tree tops hours earlier.
Low Aurora
A combination of short and tall black spruces creates a beautiful effect in this winter wonderland.
Spinning Stars in a Winter Wonderland
This starspin shot was set up for 2 hours. Focusing on the north star, it is amazing to see how much they shift over that time!

Chasing the Minnesota Aurora

During my trip home to Minnesota I have taken what I have learned about aurora watching in Alaska, and transferred it to conditions in the midwest. In doing so, I traded watching the aurora over snow drifts to squinting my eyes over bean fields with moderate success! A big push of energy from the sun has elevated geomagnetic energy to KP 6 or a G2-“Geomagnetic storm level 2”, which boosts the aurora to Minnesota, and even beyond. The two nights I chased the aurora brought success in both capturing the aurora in central Minnesota, and for playing with some new techniques which I will be honing in the upcoming year and are featured below. I would love to hear your feedback!

This timelapse below is fairly short and does not have a brilliant aurora, but does give a great idea of where to look for the aurora in Central Minnesota. During this G2 storm. In Alaska the aurora during a G2 storm would be far overhead and taking up the whole sky. In Minnesota it rose slightly above the horizon. Viewing would have been better if the smoke haze and moonlight could have been removed.

Moon through the clouds
The first night that I chased the aurora, a strong wing was rapidly pushing the clouds past this moon, which was fortunately setting. I really like the wind in the trees of this particular shot, as well as the long shadow cast by the moon.
Starlapse and Aurora
This star spin shot captures a 1.5 hours timelapse of star movement in the sky. Fortunately I captured the faint glow of aurora on low on the horizon, and directly below the pivotal star – the North Star.

One of the techniques I am very interested in growing is the ability to capture full panoramas of the milky way. The progression of images below shows a little bit on how that works. I learned a lot in this first attempt. A few key findings : 1) find the darkest skies possible! The light pollution shows here. 2) need to have more overlap in the shots 3 ) I tried to capture the whole galaxy in one sweep of the camera. I now know I can stitch multiple rows of shots to capture a larger area 4) keep the ISO of the camera low-ish to reduce noise. For those reading this with experience in capturing the Milky Way, please contact me, it would be great to pick your brain!

Midwest Milky Way
This image does a nice job of capturing a single image of the Milky Way. However, I would like to find darker skies. By taking multiple shots with the camera on the same plane, I can stick them together into the results below.
Milky Way Stretch
Here is one of the things I am struggling with in capturing a full panorama of the Milky Way. This image has a gorgeous amount of contrast, however, after stitching, I did not have enough horizon to create an image that can be cropped well. I would love to get feedback on the best way to straighten and correct these images.
Milky Way Panorama
This image is the best example I have of stitching the Milky Way, but is far from the entire arch. I do really like the bit of aurora that shows up here. Hopefully I can apply what I learned in my next attempt!
Aurora KP 6 Central Minnesota
This image of the aurora was taken in Rice, Minnesota during a G2 auroral storm. If it weren’t for the moon and the haze it would have been a much nicer show!

I have done a lot to curate my aurora gallery on Fine Art America. I would love if you checked it out!
