A small cloud shows a spectrum, cut by a contrail that also cuts through part of a circular halo.

I noticed the halo around the sun as soon as I walked out the door for lunch on Thursday. The rainbow cloud? That appeared as I walked past a building. I saw it as soon as the southern sky came into view again.

The colors got more intense over the next few minutes, and I kept taking photos until my phone locked up. I stood there watching the colors intensify, then fade, while I pulled out the battery and waited for the phone to reboot.

A man who’d been sitting nearby, buried in his phone, looked up wondering what I was taking pictures of. He’d never seen anything like it before, and wondered what it was, and fortunately I was able to answer.

At the right angle, ice crystals in a cirrus cloud refract sunlight to produce a feathery rainbow effect. The circumhorizon arc runs parallel to the horizon, and while it can be long, it’s usually only seen in fragments like this. I’ve only seen a few of these myself, and it’s been years since I’ve seen one this intense. I took this photo through my polarized sunglasses, but the colors were bright even without them.

When my phone froze, he offered to send me one of his pictures just in case mine hadn’t actually saved. Fortunately they had, and I actually posted to Flickr several hours before his message made it through the cell network.

Within a few minutes, the cloud had drifted out of alignment, and the colors had faded completely.

An hour later, on the way back from lunch, I noticed a longer patch in a smoother cloud layer, but it was faint enough that I could only barely see it with my sunglasses on. Without them, it faded completely into the glare.

If I’d had my better camera with the zoom lens, I would have gotten some better shots of just the bright cloud. Then again, I wouldn’t have been carrying it with me to lunch, and the effect was gone in the time it would have taken to run back in and get it. So it’s probably just as well I stayed and watched instead.

Funny thing: I posted a cropped view on on Instagram featuring just the arc fragment and contrail. When I went back to look at the #rainbowcloud tag last night, I found no less than SIX other photos of what was clearly the same cloud at various points in its five-minute lifetime!

Crimson Saucers: Lenticular clouds at sunset.

Out of pure luck and timing during last night’s errands, I saw this amazing view of lenticular clouds over the San Gabriel Mountains, lit up red from the side by the sunset. I knew the phone couldn’t capture it, and ran back to the car for my camera. Even that came out awfully grainy, but the colors and shapes are intact.

I caught this view of the clouds lit up by the setting sun out of the corner of my eye on the way home tonight, and decided that I had to turn around and find someplace with a relatively unobstructed view. The beach would have been perfect, but also would have taken too long. In a pinch, I picked the top of a hill along an east-west street.

At first I was reminded of a dragon, but as I watched it, I started thinking it looked like a bird. I was going to call it “Sunset Phoenix” until I realized it would sound like a sunset in Phoenix, Arizona. Neat, I suppose…but not as intriguing as a fire dragon.

A rainstorm hit Los Angeles today and cleared up in some parts of the region during late afternoon. After work I made a beeline for the nearest beach to catch the sunset, which happened to be Dockweiler Beach at the end of Imperial Highway.

The beach was absolutely deserted when I arrived (not counting the gatekeeper who dutifully collected $6 for parking), which made sense — it had been a cold, rainy day in November, and it was almost sunset besides. The sand was all wet, covered with tiny little pockmarks from the rain.

Rain was still falling in Santa Monica to the north and somewhere inland in the South Bay — possibly Torrance or Redondo Beach. Lit from the side, Santa Monica looked like there was a golden haze above the city. Continue reading
