Shooting from the Thumb

In my first post back its not so much about weather! But weather and space conditions were just right to capture a stunning sky from Caseville, MI (yes during the Cheeseburger Festival) this past weekend. With clear cool skies, a moonless night, and low light pollution I was lucky enough to capture not only the Milky Way, but also the dusty Andromeda Galaxy and a surprise visit by the Aurora!

We started out taking a few test shots from the yard as the evening sky dimmed. Stars were certainly eager to come out! With the leftover sunset light fading, my girlfriend and I went to the Saginaw Bay coastline to try shots along the beach. I had never shot over the water before. I was hopeful that if the water was calm enough, perhaps some shots could reflect the night stars and make something cool. Really didn’t know what to expect but was excited to experiment.

The Milky Way was very visible once eyes adjusted and I initially aimed my T2i with kit lens 18-55mm in that direction to see what we could find. I only brought the T2i on the beach run because it has Magic Lantern installed on the SD card, and thus has an automatic intervalometer on it. I set that up to take repetitive 15sec shots of the milky way as it paced the sky. Bumping the camera to 3200ISO, stars filled the shot, but a shot of the Milky Way at 18mm on a crop sensor camera isn’t too interesting, you need a subject! Cue the aurora borealis…

Missed the stellar noise control of the 6D on the beach, but the T2i still holds its own with a little post cancellation. I initially didn’t recognize the aurora on the horizon. Dismissed it as fog rolling in off the water. Once I saw vertical pillars, I remembered what this meant. Mid shot of the Milky Way I pivoted the camera down to double check with the long exposure of the camera sensor, and sure enough that was the aurora! After awhile the aurora calmed down and I ached for the 6D back at our current residence. With no moon out and no clouds in sight, the stars were begging for an extended photo shoot. On the walk back I stopped on a back road and just did a sample shot. The scene reminded me of a shot in upstate New York two years ago. Bonus? The Milky Way darting through…

As the night wore on, we got tired and pulled some blankets out to just lie in the back yard and keep shooting. Trees can really frame stars well! Looking northeast, the Milky Way pulled up and started to look vertical. Experimenting with some shots, I noticed a dusty ‘star’ which I would later look back in Stellarium and realize it is the Andromeda Galaxy! So many very interesting sights in the sky, and then the aurora cheering from the corner saying, “Look at me too!”

Was a great opportunity to capture the night sky in central Michigan and spend the weekend with some great folks! Thanks go out to my girlfriend’s family and grandparents for hosting!


October Lights

Some great looking Aurora for Michigan Tuesday night following a Coronal Mass Ejection from the Sun on Sunday. It finally made its way to Earth’s magnetic field! And boy was it a strong impact.

Full Tilt

Arrived to a spot just in time to catch the opening act!

I first learned about the ejection from Tamitha Skov on twitter. She posts plenty of great space weather updates, and also the science behind the sun and its Earth effects. Upon hearing that Lights in North America were possible via the NWS Space Weather Prediction Center’s Facebook Page, I thought I would at least probe the skies of Michigan later.

Around midnight things started to ramp up on the Kp Index, a rough indicator of aurora visibility. Its dark, and parking along side a rural road is a little dangerous due to unsuspecting travelers, so I decided to start small and bike across the street to an apartment complex that opened to a large field. I’m still south of some intense light pollution, so was not expecting much, but just wanted a hint.

Kp ranges. The higher the Kp number, the further south aurora may be visible. On this October night, we reached about 6.5/7 on the Kp scale.

My tripod was missing in action, so this complicated things greatly. Taking photos of the aurora requires the camera to be very steady while the picture, sometimes 8-20 seconds in length, is being taken. So I just relied on setting the camera on the ground and placing some items under the lens to prop it a bit. Turns out on my first shot I got what I was looking for. The hint. Circled is just a slight green band of aurora popping up between two patches of loud light pollution. So lets trouble shoot; northern lights = check, tripod work around = check, no light pollution = no check.

Just a taste of aurora!

Having to get up at 7am the next morning was also a negative factor, if these lights took off, I could be up for awhile.

Dew was forming on my car windows, a quick roll down of the windows and a wiper swipe and things were clear. I traveled to McDonald Park along Pickard Rd. which is west of town, and north of any obstructive light pollution.

When I got out of the car, I saw the tell-tale signs of an ongoing Northern Lights performance. What you see with your eyes is different than what the camera picks up. Aurora could look different in high latitudes then what I saw last night, but if I could describe it, it looked like an elevated fog. You could tell it was there because the sky above looked similar to sky right along the horizon, but in between… was the Lights. I modified a photo from early on to represent what I could see myself.

The camera tells a more colorful and stunning story. By having the shutter open and the camera taking a picture for 20 or so seconds, any lights in the dark sky are more pronounced. So stars are plainly visible, as well as the aurora colors. This was a few minutes after the above photo:

Lights by Man and Nature

Getting a little creative with the show still on. Timed a car going by to add a different type of light.

The sky lit up with activity right as I settled down. I mean I could actually see some vertical elements moving across the horizon to my naked eye. I teared up a bit. This was amazing. You see countless photos of the Northern Lights online(guilty here), but seeing it in the flesh, is just spine tingling. Red is apparently more rare as it is Oxygen reacting with the disturbance, and this take a little longer to process, may explain the abundance of green, but little sprites of red.

Dugout Lights

Nearby baseball field provided some foreground interest. This dugout seemed to be nicely enveloped in some lights.

If you’re interested in Aurora spotting, there are a few resources to keep an eye on. Things may get confusing along the way, but stick to sources that blend public viewing and educational. You’ll learn a lot fast!

Be patient, and be ready to be disappointed. Computer models and predictions can point to an event, but the light strength just may not cooperate. At the same time, the opposite can happen, and you may get a treat! Happy hunting!

Bitterly Cold Air Inbound

The cold will get colder next week as jet stream features carry cool air down from Western Canada (Alberta and Saskatchewan). Here is a rough ground estimated temperature from the GFS for Tuesday night. The red/blue lines show their listed temperature value, while the black lines show Mean Sea Level Pressure (MSLP) in millibars.

Thankfully, the warm nature of the Great Lakes will shield us Michiganders from the bulk of cold air. Notice how tightly the lines of temperature are packed north of Michigan indicating the strong temperature gradient. Also, directly west of Lake Michigan lies a -5F degree line, where we will stay a good 10 degrees warmer than that with lake shielding. Nonetheless, highs on Tuesday may only reach the mid teens, and the rest of the week struggles to get above 20. Nightly lows will be in the single digits, early morning commuters will be able to count the temperature with their fingers. These bitter temperatures combined with strong winds will make wind chills in the negatives, so bundle up!

As is common with cold air over a warm body of water, the lake effect snow machine will be churning. With this strong cold air mass moving through, shoreline locations will see a good bit of snow. Along the eastern shores of Lake Michigan accumulations will be as much as 6″. Lake effect snow events can vary in short-term, so will keep an eye on where accumulations will trend. (Worthwhile to note Grand Rapids NWS has a Winter Storm Watch out for counties along the Lake Michigan coast. Gaylord NWS also has Watches out for a little clipper coming across this weekend and the additional lake effect snows)

Keeping It Cool

For a little while there, I was pretty optimistic a rebound of temperatures would come by. It now looks like we are in Fall’s grip. Last Thursday was really nice when we hit the mid 70s, but the following day retaliated with highs in the 50s.

I’ve spent some time thinking of a possible research/poster for annual NWA meetings and the like. So far I’ve thought about how storm conditions show different lightning characteristics, and something about deformation snows associated with a low pressure system in winter. Both I’ve experienced.

The lightning one is interesting. Since I pull my camera out during any lighting/storm activity, I’ve likened a few traits together. High precipitation storms, where you are literally getting rinsed even if behind a plate of glass, seem to have more cloud to cloud lightning than CG (cloud to ground). This could be due to the massive amount of rain in the sky which diffuses the light about and makes it act like a giant flashbulb, or it’s just that there is a TON of lightning going on. I learned last semester that high precip rates lead to frequent lightning, because the precipitation activity creates the + and – charges needed to create a polarized environment in a cloud. I’ve noted less cloud to ground bolts in the middle of a storm, and more on the edges of storms. Again, all of this could be relative, but I can never get crisp lightning photographs in the middle of a storm.

I also was thinking about a topic about deformation snows around a negatively tilted low pressure system. While the negative tilt has more to do about the trough with the system, the low is affected. I don’t know what relationship I would like to focus on, but maybe something like trying to pinpoint that sweet spot where someone will get buried. Yea, and it will be over my house.

Anyway. What’s the weather doing? Well Tuesday looks beautiful and windy. We should hover around normal temperatures this week with a shot of rain Tuesday night.

The aurora made another appearance here in Mount Pleasant. I rallied some room-mates up and we went searching for a wide open field to get some photos. Unfortunately the back road we thought was perfect, was not perfect for someone else and they chased us off. No worries though, sure the lights will be back. Did get a couple good shots and they can be found on my flickr page. Just click on one of the photos to the right.

Wxchallenge is going on. Actually put more effort in, and after learning some things these past years, I placed well for the first city. For anyone that is new, the Wxchallenge is a collegiate contest where you must forecast for a certain city over the course of two weeks. You must enter a forecast for high and low daily temp, wind speed, and precipitation. Points are given for error. So, say I forecast 78F, but the real high temp is 74F. I would be given 4 points of temp error. Scoring plays like golf, you want to have the lowest amount of points, thus the lowest amount of error. It can get intense sometimes! Especially when you see yourself doing well, and you spend that much more time making sure your next day is going to be spot on. I finished first in our CMU student group, but barely. Another junior was just 0.1 of a point behind me, so it was pretty tight up to the last day. Did get a few mean mugs from some seniors, but the next city will be interesting. Billings, MT is located near some mountains, and they goof everything up for us flatlanders!

CMU Wxchallenge final for Pensacola, FL. Would have been nice to have someone place in the top 50, but maybe next city.
