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!

The Scoop on an Alaskan Personal Use Fishery

Alaska is famous for its rivers which fill with salmon each summer. Each species comes at an expected time, first the kings (chinoook), then the reds (sockeye), and finally the silvers (coho) and pinks. Anglers throughout the state pursue them by boat, rod-and-reel, and nets depending on the location and intent. A specific section of the Alaska fishery is deemed a “personal use fishery”. Even more so than other fishing regulations, harvest in these regions is meant to fill freezers for the upcoming winter. Alaskan residents are allowed to use a variety of nets on poles to harvest up to 25 salmon each.

Chitina River is a 112 mile tributary of the Copper River. As of July 28th, 2015, 1,341,545 sockeye salmon had made the run upriver (adfg.alaska.gov)!! The abundance of fish attracts hundreds of fishermen each day. The Chitina River is highly braided and variable in depth, and flows out of the Wrangell-St. Elias National Park from the Chitina Glacier. Because of the glacier melt, the water is chocolaty brown all year. Chitina drainage is a  truly rugged and beautiful area; the banks of the river are renowned by the anglers who walk down them for their steepness.

The Technique

I had a lot to learn before hitting the trail to the river. I was lucky that on a Friday evening it was packed wall-to-wall with fisherman. Most were standing around recounting the action of the day, cleaning fish, or planning for the next morning. I heard a group of four guys giving out tips to a fifth guy standing with them, and inched in to listen and then ask a few questions. The first thing the leader of the group emphasized was safety. Fishing in the “canyon” can be particularly treacherous due to the steep walls. Many fisherman choose to tie themselves to the rocks when fishing the canyon. Second, be ready to stay out for awhile because the fish come in pulses based on the flow of the water among other factors. Last thing was to find an eddy behind a bolder or point where the current was headed back up stream. Placing your net in the swirling, upstream current ensured it stayed open for passing fish using the eddy as an energetic rest-stop. Visibility was 0 inches due to the turbid waters from melting glaciers, so it was necessary to wait for the “bump” which signified a fish in the net. As he described the bump I could only hope I would know what he meant the next day.

Chitina River Dipnetting Technique
The eddy behind this boulder proved a perfect eddy. As you can see my net is facing up river (the current is flowing from left to right).
Chitina Shallow Eddy
The hoop on the net is pretty large, and I bottomed out in the river. This eddy provided only two fish while I stayed there.

The Result

Early in the morning we skittered down the steep banks of the Chitina River. I picked an eddy that seemed fitting, and as I dipped my net in the water its pocket billowed out perfectly. I perched expectantly on the shore and leaned lightly on the net to keep it turned open in the rushing current. As it turned out the bump was pretty distinct! Although I could not see the salmon swim into the net, I could imagine its nose hitting the mesh,  it becoming disorientated, and lying flat in the mesh bag as it was pushed sideways by the swift current. It was at that moment that I raised the net out of the water to catch my first sockeye from the Chitina. It only took 7 minutes from the time I started fishing, and I had visions of completing my 25 fish limit quickly! However, the second piece of advice became very evident to me as I stood on the banks of the river. The fish only trickled into my net, and then after 4 stopped completely. I did not catch another for the entire day.

After two days of fishing I ended with seven beautiful sockeye salmon, and although I did not “catch my limit”, I felt very grateful and blessed to be able to partake in this unique, Alaskan fishery! As important as it is to put what you need away for the winter, it is important to save a couple for the grill too! These fresh salmon on the grill with lemon pepper and olive oil, and grilled sweet potatoes was as good as it gets, and a gratifying way to celebrate a successful trip to the Chitina River.

Salmon Grilling Steps
Total time for this salmon on the grill is ~ 13 minutes. 8 minutes on the meat side to keep the moisture in and then 5 minutes on the skin side to finish cooking it!
