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.

It was clear enough that I could see the silhouette of Catalina Island off in the distance to the south (though I didn’t get any good photos of it). I was surprised at how much more I could see from the beach than from my office window, only a couple of miles inland. (I have to remember: LAX is huge.)

As the sun dipped below the horizon, it lit up a column of clouds red from below. Even afterward, it lit up the edges of distant clouds just barely visible peeking over the horizon.

The rain started up again as I left, getting stronger as I drove inland. By the time I got home, I was ready to use an umbrella just walking from the garage to the front door. About a minute later, it really opened up, and I made the mistake of going out to check the mail. Instant soak.

This was the view that surprised me the most: Bright orange (a little more magenta in real life than it looks here in the photo) on the underside of the clouds, but plain gray on the sides.

Here are a couple of views of the rainbow and Downtown Los Angeles in the distance, a little bit earlier.

Looking northwest across LAX toward the Santa Monica Mountains. The sun is out of frame to the left. Oh, who am I kidding? It was behind a building, so I aimed at what I could see.

Believe it or not, this is looking *away* from the sun. Sun rays are (at this distance, anyway) basically parallel, and a trick of perspective makes it look like they converge toward the sun or, in this direction, toward the point exactly opposite, like looking down a long hallway.

Ever since I read that these were possible under the right circumstances, I’ve been hoping to spot them and (if possible) photograph them. I saw some once while looking toward the mountains a year or two ago, but they were too faint to photograph. Naturally, when I finally saw them again, I was driving, and didn’t have time to stop and aim. Amazingly enough, one of the photos I took just pointing the camera out the window actually caught the rays!

Contrast enhanced to make the rays more visible. You can also check out the unmodified version.

The flight path, distance and viewing angle made it look like the airplane was the same size as the Moon, and it passed by just below the crescent.

If only I’d had a camera, preferably one with really fast film and a good zoom lens…

I saw this amazing circumhorizon arc around 1:30 this afternoon. I had just crossed the street while walking to lunch when I looked up, saw it…and walked back to the office to get my camera!

Lesson learned: always bring the camera!*

It started out as just a couple of small segments, but as the clouds drifted into position it quickly grew, and at its strongest it was just long enough to fill the field of view on my camera. There were also a couple of fragments of a 22° circular halo visible at the time.

The whole thing had vanished by 1:50, as the clouds drifted out of alignment, though I did see a more complete circular halo later on.

It looks like a sort of straightened-out rainbow, but it’s actually caused by ice crystals. If the right type of crystals cover the entire sky, this will actually stretch in a circle all the way around the sky, parallel to the horizon.

They’re a lot less common than the 22-degree halos. I’ve seen and photographed a ton of those over just a few years, but this is maybe the second time I’ve seen something like this. Fourth if you count the two feathery fragments I’ve seen.

At times like this, I really wish I had a DSLR, but the point-and-shoot will do in a pinch.

*On the other hand, when I went back, I pointed it out to a couple of people at the office who are into photography, since it was visible through the windows on one side of the building. One of my co-workers has a digital SLR and carries it with him, so he went outside and got some great shots. If I hadn’t taken a late lunch and chosen to walk anyway and been in the habit of looking for halos and forgotten to bring my camera, chances are no one in the office would have seen it.

Update (May 17): I just discovered that there are people who think these clouds are connected to earthquakes. No, they aren’t. They’re caused by ice crystals refracting sunlight, just like most halos, and have been seen in many places that didn’t have earthquakes.

A mosaic of four photos I took this afternoon of a full 22° halo around the sun. It was extremely hazy, and the halo was almost impossible to see without sunglasses because of the glare. I actually stopped the exposure down in order to get the halo.

A few minutes earlier (and a few miles away) I also saw a faint fragment of a circumhorizontal arc. Oddly enough, it was the same time of day, time of year, direction of the sky, and stretch of road as the last one I saw! If I drove that stretch of road regularly, I wouldn’t be so surprised, but I’m only rarely in that area at lunchtime.

Update: About a month later, I saw a really clear circumhorizon arc (or rainbow cloud)…from my office building’s parking lot!

At the age of 34, I’ve finally seen the planet Mercury.* It’s notoriously difficult to spot, but when I read that it was going to be very close to Venus for the next few days, I had to try.

As it turns out, I was able to see it from a local grocery store parking lot. I left the car just as Venus was becoming visible, concerned by the clouds starting to drift past, and left the store to a clear twilight sky and a “star” below and to the right of Venus…exactly where Mercury should be!

*Of course I’ve seen photos, but I’d never seen the planet directly with my own eyes — or if I have, I didn’t recognize it.

I only used the coffee mug because it was something handy with which I could block the sun. Still, I kind of like the “Behold…Coffee!” effect. OK, it’s not quite on a level with Heterodyne Coffee, but what is?

I spotted a great 22° halo around the sun this morning, almost by accident. There was a reflection in the rear window of the car in front of me that looked like it could be a distorted contrail or it could be a distorted halo. Once I parked, I looked — and there was this clear halo, almost 3/4 of the circle. The missing quadrant was to the lower right, so I just framed this to get as much of the visible part as I could.

It wasn’t really this blue. The G1 tends to make images in daylight a little extra blue, and seems to have really gone overboard on this one. I’ve got to remember to bring the regular camera with me more often!

While driving around lunchtime, I saw an airplane pass overhead, its contrail casting a shadow on the thin cloud layer below. I had my camera handy, and was stopped at an intersection, so I snapped a couple of shots. As often seems to happen, the first, haphazard one was the best.

The diagonal line extending down from the sun is, I believe, a sun pillar-like effect in the trails left by the windshield wipers. Also: Unless I’m mistaken, you can just barely see the edge of a halo in the feathery clouds at bottom center. It’s the slight reddening.

A few hours earlier, I saw this:

I glanced out the window while changing lanes on the freeway this morning & noticed the bottom edge of this halo. By the time I had a chance to stop the car and really look, the lower arc seemed to have disappeared, but the left side was sharply visible – as was a sundog. I rolled down the window and snapped a couple of photos while waiting for the light to change. Unfortunately, I couldn’t position anything to block the sun, so the exposure isn’t all that great.

By the time I reached my destination and parked, it had all faded except for a slightly bright patch in the clouds to the left.
