What surprised me is that the halo was not only still there after lunch, but clearer. On the way back, I stopped in several places with a building, or a sign, or a tree blocking the sun. The curve seemed too shallow to be a standard circular halo, so I wondered what I was actually seeing. Then I realized there was a faint halo inside the brighter curve, the two fragments meeting above the sun and splitting like diverging roads.

Then I noticed the sundog.

Three distinct sun halos. Not complete, and far from the clearest display I’ve seen, but certainly the most complex.

The brightest part appears to be the top of a circumscribed halo, which varies in shape from oval to kidney-bean depending on how high the sun is. You can just see the 22° circular halo branching off below it. Off to the right is a sundog.

It’s too bad I only had the phone, but it did manage to catch all three halos. I fiddled with the contrast a little to make them clearer, but they are visible without it.

And to think I saw this from the middle of suburban Southern California!

Sundog, originally uploaded by Kelson.

Friday was a good day for atmospheric optics. I watched a sundog for most of my drive home.

We stopped the car, found a tree to block the sun, and both looked. There was so much glare it was easier to see with sunglasses on, so I lent mine to Katie so she could catch it. Finally I grabbed the camera and took a few pictures, most of them using a gate post instead of the tree.

We ran some more errands, and I caught up with her at the grocery store. On my way from the car, I looked up and saw a perfect bright sundog to the right of the sun, much brighter than the clouds around it and showing the full red-to-blue spectrum. I should have gone back to the car for the better camera, but I used my phone camera instead, and got this shot.

I got to the edge of the lot just as Katie was leaving, and immediately said something like, “Look! Right above that palm tree!” Then I took off my sunglasses, realized that it was completely washed out without them (though it seems to have come out all right on my cheesy phone camera), and handed them over again. It continued to be visible, though less well-defined (it was a lot sharper than this photo shows) for at least half an hour.

A circle around the sun, and a bright rainbow-colored spot in the sky. I wonder how many people walking around never even noticed.

The picture on the left was the best of the set, with the best contrast. The red is clearly visible on the end toward the sun, and the reflection is clearly brighter than the surrounding clouds. The one on the right is actually two minutes earlier, and isn’t as good — except that it looks like there are two sundogs (something I hadn’t noticed when I took the picture). Presumably there was a gap in the cloud of ice crystals, and one half or the other drifted out of alignment.

Coincidentally, that was the same day that aeryncrichton sent me a link to these sky phenomena photos. They’ve got several halos, a pair of auroras, a double rainbow with supernumeraries, and a photo of star trails (which is technically a photographic artifact, but still looks nifty).

At least, I’m pretty sure that’s what it was, given the positioning, the brightness, and the reddish coloring on the end nearest the sun. The sharp edges of the reflecting cloud (a fragment of a contrail?) make it look a bit odd, though, like someone cut out a chunk of sunlight and pasted it into the sky.

Here’s a closer view from about a minute later.

I was following my usual photo-while driving method of pointing the camera in roughly the right direction, click the button a bunch of times, and hope a few shots come out. (Hooray for digital cameras, where you can delete a bad photo instead of wasting film!)

First up is a twilight view of South Coast Plaza. On Friday the 13th, we went to the nearest Borders to pick up The End of Lemony Snicket’s Series of Unfortunate Events and Neil Gaiman’s new short story collection, Fragile Things. We ended up crossing the bridge over to the main section of the mall, turned around, and saw an amazing twilight display with clouds silhouetted against the blue.

We stopped to take pictures. We weren’t the only ones.

Perhaps an hour later, the rainstorm arrived.

Next up is from this past Monday, October 23. I was driving up the 405 after work and noticed that there were some feathery clouds in the right area, so I started looking for sundogs. Normally I don’t find anything. It’s Southern California, after all, so the right conditions are relatively rare. (Though occasionally I see something spectacular like the full halo I caught in February.)

To my surprise, I saw a faint bright spot in the clouds, level with and to the right of the sun. It got brighter over the course of my drive, with hints of red, orange and yellow creeping in on the sunward side: a classic sundog. Once I got onto city streets, I had a chance to stop and take a picture.
