View 1: Jupiter is visible, but the moon oversaturates the camera. In the other: The moon is clear, but Jupiter is too dim to see.

I walked out to get the laundry tonight, looked up and saw the moon and Jupiter practically next to each other. I took a quick shot with the phone, then went back in to get a better camera. (Unfortunately, the best camera I have is in the shop right now.) The phone picture is at upper left, the camera picture at lower right.

Nothing makes you appreciate how bright the moon really is like trying to avoid overexposing it without making the second brightest planet disappear.

I had several plans for viewing today’s solar eclipse, depending on the weather. As the hour approached and clouds loomed in the west, I decided that my best bet would be to get above the cloud cover, and drove up into the hills to Del Cerro Park at the top of the Palos Verdes peninsula.

I’m glad I did, because a lot of other people had the same idea.

Individuals, couples, families, groups of friends, groups from schools — and everyone had a different way to see the eclipse: pinhole cameras, binoculars projecting on cardboard, welding helmets, “eclipse glasses” and more. There were also people who were just out for a day at the park, and wanted to know what was going on.

If J had been a few years older it would have been a family event for us too, but at a year and a half, I don’t think I would have been able to explain anything beyond “don’t look at the sun.” A partial eclipse is easy to miss if you’re not paying attention.

I’d cobbled together a pinhole camera the day before from two Amazon boxes, a sheet of paper, a sheet of aluminum foil, and lots and lots of packing tape. I actually started with just one box and I decided the image wasn’t big enough, so I grafted on a second. Even then it was only about 3/8″ across, but when testing it I could see the edges of clouds drifting across the sun, so I figured it would work. It did. Continue reading

Just yesterday, I had no idea there was going to be a lunar eclipse this morning. Then I skimmed an article somewhere and got the impression it was only going to be visible on the east coast, And then I read about it on Bad Astronomy and realized I had it backward. Not only would I be able to see part of the eclipse, but I’d be able to see the moon in totality! All I had to do was get up early in the morning and find a place with a clear view of the western horizon. I considered driving down to the beach at 5am, but thought I’d start out by seeing how visible it was from home. As it turns out, I should have gone to the beach to start with, but I had some good viewing before I left.

So I set my alarm, woke up at 5am (plus the snooze button), and went out to see what I could see. To my surprise, I actually had a decent view of the partially-eclipsed moon from across the street. It was about half-covered at this point (as shown in the first photo above). So I stayed out there for a few minutes deciding what I wanted to do, went back in to have some coffee and breakfast, then went back out shortly before 6 to watch as the umbra covered the disc the rest of the way. I found it interesting that it didn’t look particularly reddish this time, just brown.

Awesome viewing, though it was clear the moon would dip below the roofs of the houses soon. I needed a less obstructed view.

As soon as the moon went into totality, I went back inside, woke up Katie just enough to let her know I was going, tossed the rest of my coffee in a travel mug and hightailed it down to the beach. Continue reading

I’m 90% certain that I managed to (barely) spot Mercury below and to the left of Venus from the grocery store parking lot just after sunset. Appropriately enough, the one other time I think I spotted Mercury, it was also from a grocery store parking lot.

It was like trying to spot one slightly brighter pixel on a high-resolution display in the middle of a gradient. Faint enough that if I hadn’t seen it in the same place each time I looked, I would have dismissed it as something in my eye, or part of an after-image. I couldn’t really see much more than the fact that there was something there where Google Sky Map said Mercury should be.

It’s really neat that Jupiter and Venus sort of bracketed the twilight sky!

Venus and Mercury

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.
