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 couldn’t remember whether Venus was visible in the evening or morning (or at all) right now. It was roughly in the direction of an airport, so it could easily have been a helicopter or an airplane traveling at an angle roughly in line with my line of sight. By the time I got home, buildings and trees blocked the horizon, so I didn’t think much more of it.

I’m in California. Interestingly enough, thousands of miles away in Ohio, people have been seeing a bright light in the west every night for the past week and making UFO reports.

Last night I decided to see how early I could spot Venus, and caught it fairly high in the sky just after sunset. It was hard to see without really looking for it because the sky was still light, but it became a lot easier as the sky darkened. Not surprisingly, as it set and brightened in the dimming sky, it passed through roughly the area I remembered seeing the unidentified light last week. Mystery solved.

I don’t understand why, in a world full of airplanes, helicopters and the occasional blimp — not to mention a world where we see stars and planets every night (barring clouds and light pollution) — people jump past these mundane explanations when they see a light in the night sky and decide it must be an alien spacecraft.

The first two shots were taken at twilight (well, dusk, really), around 5:05–5:10 PM PST, while the third was taken at 5:30, after night had fallen.

It’s really odd to walk out of the building into a lot that’s normally lighted (even when I head in to do emergency server maintenance at midnight) and see it completely dark.

Well, not completely dark. There was a little light leaking from windows behind me, and streetlights filtering through trees, and what I could see of the sign on the building across the street. Nothing compared to some of the camping trips I’ve been on, or the drive through Ka‘u at night. But for a suburban office building, it was a change.

Edit: Oops! For some reason I’ve been convinced that this was Saturn, but it’s actually Jupiter.

First, remember on our most recent trip to Las Vegas (last March) we repeatedly encountered a slow-moving, hand-painted truck labeled “Henry’s Moving” on the drive out. Well, after a trip to Fry’s this past Sunday, we spotted it again.

Second, for the first time in 1½ years, I managed to spot Venus in broad daylight again. I went downstairs to grab a snack about 3:20 this afternoon, and noticed the first-quarter moon in the East. Remembering how I located Venus the first time, and already in the shadow of the building, I traced a line from the moon toward the sun, and found it, a tiny white point in the light blue sky. It was almost directly overhead, and just outside the area around the sun where the sky turns increasingly white. I lost sight of it, but managed to locate it again before I went into the cafe, and once more when I walked out.

I probably looked silly, staring straight up at the sky. But hey, how often do you see another planet during the day?

Edit: I went back down a few minutes later and took a photo. It actually showed up, which seriously surprised me.

My parents gave me a flexible mini-tripod for Christmas, and it proved very helpful here, as there was nowhere flat where I could set the camera and still get a good view. I ended up coiling it around a stair railing, which held the camera in place long enough to get a decent exposure.

I seriously thought about pulling my SLR camera out of the closet and seeing whether I had any film for it, but ultimately decided against it.

Someone on Slashdot mentioned it was possible last week. I took it seriously because back in high school, I used to watch Venus fade into the brightening sky on winter mornings. Often I could still find it once I arrived at school, since I knew exactly where to look.

I tried unsuccessfully a couple of times over the past week, but today I had a ~20-minute walk mostly facing southward, so I thought I’d give it a shot.

I used the Moon as a guide, trying to guess the distance based on how far apart they were last night. As I passed through a building’s shadow, I spotted a stationary white dot in the right area, a bit more than a hand span away from the crescent Moon in the direction of the sun, barely visible next to some wispy clouds. I couldn’t find any sign of a con trail, and it didn’t move, so it clearly wasn’t an airplane, but I was able to look away and back and still see it.

I caught it again from the mall itself, about 15 minutes later after I finished eating and started walking back. This time I was able to peg it down as the distance from one eye’s image of my thumb to the other eye’s image of my little finger. Same place, no sign of movement. Could be a weather balloon, but still…

I kept pausing next to trees or traffic signals to look for it again on the way back, but couldn’t spot it again until I walked into the shadow of another building. Apparently just blocking the sun’s glare wasn’t enough, I had to let my eyes adjust for a few seconds. But it was right there, in clear sky this time, and I was able to walk past a few trees and find it again within seconds.

One final test: as I reached the building where I work, I walked around to the far side to put myself in its shadow. A few seconds to let my eyes adjust, an outstretched hand, and *bam*, there it was!

First sighting: 12:52pm. Last: about 1:35pm.
