Geminids with a Side of Turkey

I spent the night of December 13/14 in my favorite meteor watching field on the Bamberger Ranch Preserve (thanks to David and Lois, respectively, for making that possible). I was counting, and, most of all, trying to photograph, Geminid meteors. Watching commenced in earnest only after I’d finished setting-up my camera and started it clicking away at 11:56 PM. It was freezing up there, and when the wind blew … much worse. The correct attire for Geminid watching even in the Texas hill country is a zero degree sleeping bag. What my meteor watching brethren in colder territories do to survive, I don’t know. (Layers are probably the key. Undoubtedly a sleeping bag would still be a good start, then wrapping that in a well heated house should just about do the trick.)

Anyway, I gave up at 6:10 AM as the sky started to brighten prior to sunrise. During those 6¼ hours, I counted five hundred and five meteors (a personal record), ranging in appearance from so faint they were barely visible, to bright enough that they briefly left a little glow in the sky after they burned-out. My camera seems to have caught at least 34 of them, but I wouldn’t describe any of the photos as remarkable. The best meteors, as usual, fell outside the small patch of sky I was photographing – though they were everywhere else at one time or another. Disappointing, but you can’t win, if you don’t play. (Conversely, if you don’t play, you also can’t loose.)

More later.

And now, a flock of wild turkeys I surprised as I was heading out of the ranch. This photo captures only a tiny fragment of the flock, but they started flying into the trees or briskly striding away even before I’d managed to stop the truck and grab the camera that I had ready & waiting for this eventuality. Still, I’ve been bumping into this flock for years, and this is the best turkey photo I’ve come up with so far.

Geminids Tonight

The peak of the Geminid meteor shower will be tonight, December 13/14. According to NASA’s Fluxtimator, it promises to be a very good show, peaking at a rate of 66.7 meteors per hour in countryside viewing conditions at 12:16 AM CST. Even as early as 9 PM, which is as early as the Fluxtimator will predict, there should be 46.8 meteors per hour. The only problem around here is the weather, which doesn't look very promising.

Weekend Links

From a book I happen to be reading at the moment:

[...T]his was real work too, something more than mere labor—time put in for pay. [....] At the end we would have something to show for it, would have added something to the stock of reality—to what Hannah Arendt once called the “huge arsenal of the given.” In The Human Condition Arendt writes of the privileged position of homo faber, man the maker of things, whom the Greeks believed stood not only above the laborer, but above even the man of action and the man of thought, or words. The laborer produces nothing lasting he can call his own, and both the man of action and the man of thought are ultimately dependent on other people, without whose regard and remembrance their deeds and creations do not matter or endure.

A Place of My Own: The Architecture of Daydreams by Michael Pollan, pg. 165.


And Now, The Links

Bamberger Ranch Preserve Gets an Observatory

I finally get to show my photo of the XXXXXXXXXXX that David Bamberger embargoed until he could make his official announcement on-line: The Bamberger Ranch Preserve now has an observatory, as you can see below.

That was a 30-second, ISO 400 exposure shot by moonlight using a 10mm lens at f/4.5. Because the auto-focus system on my camera didn't have enough light to operate, the focus was accomplished with a bit of luck and a binary search.

The observatory will be a great addition to the Preserve's education programs, and is located within an easy walk of the the Center (see my panorama of the main room of the Center), where groups of school kids come to spend as many as three days participating in educational activities. For myself, despite the moonlit sky, I was able to see Jupiter’s clouds first-hand, for the first-time in my life.
