Sun Dogs and Other Random Things
Feb. 10th, 2012 09:27 amA sun dog or sundog, scientific name parhelion (plural parhelia) from Greek παρήλιον (parēlion), meaning "beside the sun" (also called a mock sun or a phantom sun), is an atmospheric phenomenon that creates bright spots of light in the sky, often on a luminous ring or halo on either side of the sun.
Sundogs may appear as a colored patch of light to the left or right of the sun, 22° distant and at the same distance above the horizon as the sun, and in ice halos. They can be seen anywhere in the world during any season, but they are not always obvious or bright. Sundogs are best seen and are most conspicuous when the sun is low.

Driving to work this morning, I was entranced by a sun dog. It wasn't particularly strong and for that matter, I couldn't see it without either looking at it through the polarized portion of my windshield or my sunglasses. But it was mesmerizing - this patch of rainbow sky - a parenthesis to the sun. It lacked it's partner, though - at least as I could see.
I've taken to driving the scenic route to the office - not because it's scenic (that's just a bonus) but because it takes less time. The expressway is the direct route, a straight line for 13 miles or so, and it rarely gets backed up (my office is south and east, the opposite direction of most commuter traffic). But when I have to get off the highway, the traffic has become insane. Just before I get to my office, I have to deal with a huge and busy huge intersection where the north-south and east-west turning lanes can't go simultaneously. If I miss the light, it's almost three minutes before I can try again. Once school is in session, it takes an average of nine minutes to make that turn.
By taking the scenic route, it's 3 miles longer, but about 8 minutes shorter most mornings. And today, as an extra special bonus, I got the sun dog. The sky was particularly beautiful, filled with a patchwork of high cirrus clouds, gilded by the rising sun. I'm not a particularly good morning person (aesthetically, I prefer sunset to sunrise), but this was a good one. Hopefully a harbinger of the day to come.
