About a month ago I posted about noticing the Belt of Venus—the red band that circles the entire horizon just after sunset—and the Earth’s shadow on the sky. I snapped this picture on the drive home this evening. This is looking east, away from the setting sun.

Looking east toward Saddleback at sunset.

If you look at the right edge of the picture, behind the silhouette of the tree, you can just see the red band fading into the dark gray of the Earth’s shadow.

(And to think, I almost brought the good camera with me this morning… Update: It turns out that I did bring it, and just didn’t realize it was there. Oh, well.)

A few nights ago I was walking around sunset, and decided to look for something that had been mentioned last week on the Astronomy Picture of the Day: the Belt of Venus.

Somehow I’d never noticed that after sunset, the band of red encircles the entire sky at the horizon. Even more amazing, if you look away from the sun you can actually see the Earth’s shadow on the sky as a slightly darker blue below the pink. It reminded me of the view of Mauna Kea’s shadow on the cloud layer below. Oddly, though I didn’t pay any attention to it at the time, the Belt of Venus is clearly visible in that photo!

I guess at sunset I’m most likely to be looking at, well, the sunset. Or focusing on whatever it is I’m doing at the time.

This was Thursday night, so the moon was almost full. It rose just below the Belt of Venus, just inside the shadow. So close to the horizon, the moon illusion was in full effect, and it looked huge!

And me without my camera. *sigh*

Well, June Gloom seems to be over, and we’re now into the time of year when we get hot, sunny days with lots of clouds. Big, towering cumulus clouds, often with anvil heads, promising shade and rain to cool things down. The teases.

Yeah, we see those clouds most afternoons—on the horizon, just on the other side of the coastal mountains!

While it’s great for summer activities—beach trips, swimming, hiking, etc.—it can also be frustrating when you have to choose between running your electricity-guzzling air conditioner all day or leaving your window open all night. The clouds are right there, taunting you with relief from the heat—relief that will not come.

Clouds on the horizon

When I was in high school, my family took a vacation across the Great American SouthwestTM. We went to Bryce Canyon, Zion Canyon, and the Grand Canyon. We drove out to Mesa Verde, which wasn’t a canyon, but there were still a lot of cliffs. We came back through Arizona, where we stopped by Meteor Crater and Sunset Crater. We joked that it was a tour of all the big holes in the ground. (A few years later, I posted some photos from this trip online.)

The weird thing about it was that we went during August, and we got rained on at least briefly almost every afternoon—but only outside of California. Utah? Rain. Arizona? Rain. Colorado? Rain. I don’t think we got rained on during our three hours in Nevada (we stopped at Valley of Fire on the way out), but as I recall, the rain stopped about the time we crossed from Arizona back into California.

We don’t get summer storms much here in SoCal.
