And Now For Something Completely Different

I was in Lethbridge, AB this past week and noticed that the Moon was up during the day. There is a neat looking bridge there called the High Level Bridge. It is used by trains to cross a large valley. It is the largest of it's kind in the world. I've been wanting to photograph it for some time now and finally had the chance. I went out on a day when there was little cloud cover and the Moon was visible during the day.

It also gave me a good chance to finally use my Canon 40D. I will be posting pictures taken with the Canon soon, but for now, here are the photos taken with my Nikon D90.

Sundog Days of Winter

"Dazzle mine eyes, or do I see three suns?"
Shakespeare - Henry VI, Part 3

The word sun dog (or sundog) originates from the Greek word par─ôlion, meaning "beside the sun". The scientific name is parhelion, plural parhelia. It's essentially a phenomenon in the atmosphere formed by plate shaped hexagonal ice crystals (in high and cold cirrus clouds) that create bright spots of light, often a luminous ring (or halo), on either side of the Sun. The ice crystals are called diamond dust and drift in the air at a low level. Sundogs orrur when the Sun is at a 45 degree angle and is at its lowest point. Sundogs may appear as a colored patch of light, typically displaying the colors of the rainbow (red closest to the Sun, with orange then blue farthest out) to the left or right of the sun at the same distance above the horizon as the sun. They can be seen anywhere in the world during any season, but they are not always obvious or bright. Here in Canada, they are most prevalent during the winter months when the air is coldest and more ice crystals are in the sky.

Below is the first-ever photo of a sundog taken be myself in January 2010.
