Whoah, got a day behind again. What a bummer! I don’t know what happened to the clock yesterday. It kept moving in big, sporadic jumps. I had intended to tell you about Saturday evening at Kranket Island where we had a party for Jo Noble’s birthday, but now I’ve already forgotten most of it.
I know that there is a proper name for this effect, but I can’t remember it right now. It’s 05:00 and I’m not going to trudge through Google to find it. I’ll count on a knowledgeable reader to leave a comment. The effect lasted less than five minutes.
The curve that you see in the ray on the right is an effect of the way which I took the panorama shots. The image is made up of about seven frames. Of course, the boat was sloshing around a lot, so it was difficult to hold the camera perfectly straight. The image covers about 150°
Here is a single frame image of the centre of the scene:
The main ray on the right side shoots up (or down, rather) past the huge cumulonimbus incus cloud on the horizon, which is still catching the last rays of the sun, reddened by their passage through the dusty lower atmosphere. I think that these rays are shadows of clouds near the horizon in the West. They appear to converge on the Eastern horizon at a point opposite the sun because they are passing through the atmosphere at a low angle and are visible for a long distance. Think of a pair of straight railroad tracks stretching off to the horizon. They seem to meet at a point in the far distance.
Okay, if that isn’t geeky enough for you how about the pileus cloud cap on the top of this towering cumulus cloud:
The pileus is the fuzzy little hat sitting on top of the cloud. It is formed when the cloud is rising very rapidly, pushing warmer, wetter air up into cooler areas. The moisture condenses out into a little lens-shaped cap which folds over the top of the main cloud.
The image is actually upside-down. I found him under a ledge and could barely see him. I had to stand on my head and shoot to get the image. This fills your sinuses full of salt water pretty quickly. It usually produces a few good sneezes when you get right-side-up again. Sneezing into a regulator underwater is an amusing experience.
I’ll throw in one more reddish thing before moving on. This lumbering, spiky critter is a kind of Sea Cucumber, specifically (Thelenota rubralineata):
The rubralineata is one of the more colourful Sea Slugs. I have another picture of one here.
Well, that’s it for yesterday’s post. I have to hurry on to today’s post or I’ll miss the sunrise.
