Tonight was a close conjunction of the Moon and Jupiter. I had heard about this, but didn’t really pay attention until I saw a picture of it posted by Dave Palmer, who does some nice photography. So I went outside to see if I could get a picture of it. I’ve tried to photograph things in the sky before, and it’s always an interesting exercise.

I put the 300mm zoom lens on the camera, and I mounted it on a tripod with a remote shutter release. I set it on manual mode and started playing with the settings. I had to go back inside to consult the manual to find out how to change the f-stop. Since I was having to focus manually, I thought that stopping down the lens might help to make the focus a bit sharper, since there was plenty of light to work with. I tried a lot of different exposures to see what gave the nicest balance of gray shading on the Moon. I ended up with f16, 1/15 second exposure on 200 iso, and it came out pretty well for just experimenting on on the driveway.

Today was the transit of Venus, and I was ready with my small telescope and solar filter. I was home most of the day because the big oak tree in my back yard was being trimmed. That took a good part of the day, and by the time they were done, it was just about time for the show. So I set the telescope up on the driveway and settled in.

My astrophotography rig, such as it is, consists of my Canon A570 camera attached to the eyepiece of the telescope with some packing tape. It’s pretty simple, but it works. The first photo shows the Sun just before the start of the transit. The second was taken when Venus was fully in front of the Sun, which was about 30 minutes in. The other photos were just taken at random times along the way. Sunset was just after the mid-point of the transit, so the last photo was taken just about the mid-point. And of course, while I was doing this, the neighbors were stopping by to look at it, and I even had some people who just happened to be passing by stop for a look.

All told, it made for a fun afternoon. And that’s a good thing, since it won’t happen again until the year 2117.

Today was a solar eclipse. Here in L.A., we’re too far south to see the full annular eclipse, but we still got something like 85% coverage, which was still fairly dramatic.

I got a little solar filter for my Meade 2045, which is my ’small and portable’ scope. I set it up in front of our neighbor’s house where there was a clear view through the trees. I was even able to get some pictures by just duct-taping my little Canon A560 to the eyepiece. So the first photo shows the sun just a few minutes after first contact. The second is at maximum coverage. And the third photo shows the little crescent suns projected on our neighbor’s house by the sunlight filtering through the trees.

It was good geek fun. All the neighbors came out to look at it. And now that I have the filter, I’m ready for the transit of Venus on June 5th.

I was tending to the Earthquake Notification Service admin email today, and I found this in the incoming mail queue:

To: ens@usgs.gov

Subject: Your email has been discarded.

Your email sent to [redacted]@us.aflac.com with subject line of: 2012-04-05 20:23:55 (Md 3.2) PUERTO RICO REGION 19.1 -65.1 (5121e), contains inappropriate content within the subject or body of the message and has triggered the Aflac Associate message filters. The message was discarded because of the inappropriate content.

So I went and had a look at the message, just to see what it was they might be complaining about. And here it is:

Sheesh.

The Earthquake Notification Service, aka My Pet Project, just went over 300,000 subscribers. The small earthquakes in the San Francisco Bay area last Thursday had it close when I went home on Friday, and then the big earthquake in Turkey over the weekend pushed it over.

I still have a hard time believing that something I built is being used by so many people.

It’s the Google Maps Street View bicycle. Well, tricycle, but you get the idea. I saw this guy riding around through the Caltech campus today. He said the idea is so that Street View can work along bicycle and walking routes.

We’re redoing the computer room at my office. So the last couple of weeks have been very busy. We got new racks for the computers, and we’re putting them in in a single row across the room. Being that we do earthquakes, everything has to be bolted down. So today I did a little spelunking. The guy who usually does this was on vacation today, so I brought a change of clothes and a flashlight. Besides, as I always say, “how bad could it be?” I crawled around in some seriously tiny caves in Texas, and got very, very dirty, and that was fun.

The foundation of the building is kind of weird. It’s not just a big open crawlspace. It was a kind of a maze to get there, but when I got under the computer room, it was pretty obvious. The air conditioning ducts run under there, so they take up a good bit of the height, which is far from generous to begin with. So yes, it was pretty difficult and not too pleasant. And the caves in Texas were all wet inside, so the dirt was all in the form of mud, which doesn’t raise dust like the bone-dry dirt underneath the office. Yick. But I bagged my bolts and got that rack attached to the floor. In any event, it certainly made for an unusual day, although I did feel kind of dirty and dusty for the rest of the day.

There was a fairly large earthquake in Virginia today. Magnitude 5.8, which was strong enough to be felt as far north as Toronto. This is an unusual event, and it brought the news trucks out to the office for the first time in quite a while.

My Pet Project told me about the earthquake first, with a message that it had been detected by the Alaska Tsunami Warning Center’s seismic network. Given that this was an unusual location for an earthquake that large, I wanted to get independent verification that it was real. So I had a look at Twitter. And sure enough, there were people talking about it already. So I had a look at the web servers to see that they were doing all right, and I checked on the ENS (aka My Pet Project) database to be sure it was doing all right. Then I headed across the street.

Channel 7 was the first to arrive. Seeing that first news truck after an earthquake is like seeing the first robin of spring. Soon, we had a large collection of them parked all around the building, and they filled up the media room for the quick press conference that was organized for the occasion.

It’s always entertaining watching the media frenzy after an earthquake. So it made for a fun afternoon. And ENS picked up over 2,600 new subscribers today. It still boggles my mind that something I invented is being used by more than 280,000 people.

Tonight, Kathleen and I went to the Central Library in downtown Los Angeles for a talk by Annie Jacobsen about her new book, Area 51: An Uncensored History of America’s Top Secret Military Base. The format of the talk was a conversation between her and M.G. Lord, author of Astro Turf: The Private Life of Rocket Science. We’d been to one of these events once before, when we went to see John Waters last year.

The talk was very interesting and entertaining. There were even three of her sources in the audience: Ed Lovick, Ken Collins, and Wayne Pendleton. They were engineers and a test pilot on the A-12 “Oxcart” project, which was the CIA precursor to the Air Force’s SR-71 Blackbird spy plane. So as you might imagine, they had some good stories to tell her for the book. Apparently, a lot of this was classified until pretty recently. The fact that the CIA was actively designing stealth aircraft in 1957 was kept secret until the late 1990s.

All told, it was an entertaining evening. And as a little bonus, we got to look across the street from the library and gaze up at the U.S. Bank tower and think about just how much it’s going to hurt when we go to climb the stairs there in September.

Tonight, Kathleen and I went over to Hollywood Forever for a special screening of “The Captains“. This is a documentary by William Shatner, where he goes to meet and interview all of the actors who have played starship captains in all the incarnations of “Star Trek“. It was a chance for him to confront and embrace what is surely his legacy, and to talk with the others and share their feelings on their participation in “Star Trek”, which will likely be the one thing they will all be remembered best for having done.

As one would expect, there were lots of fans there in “Star Trek” costumes. I don’t have a costume, but I brought along my tribble. And each incarnation of the show and each captain had its own set of fans. Even after all these years, it’s still an amazing thing that it took on a life of its own and became such a pervasive part of our culture.

William Shatner was there to introduce the film. Beforehand, I saw him in the middle of a little scrum of photographer, along with Henry Rollins. (WTF? Henry Rollins? What’s he doing here?) In his introduction to the film, Shatner spoke of how strange it was to be introducing this film at the cemetery in Hollywood. Looking over the back wall, we could see the sound stage where they filmed the original “Star Trek”, nearly 50 years ago. He talked about how he originally came to the part of Captain Kirk, and how nobody really thought the show would amount to much in the long run. And his having to come to terms with the fact that that one role has in many ways come to define his life. Apparently, it’s been an interesting journey.

The film itself was very entertaining. The other captains all came into it with at least a bit more warning that they were doing something that would be career-defining, since they all came along after “Star Trek” had become a worldwide phenomenon. Each one had a slightly different take on how their character should work, and hearing their reminiscences was a lot of fun.

In the end, Shatner came to terms with his legacy, which was the main reason he made this film. It was a lot of fun, and I highly recommend it.
