Thuban‒The Once and Future Pole Star

Original article appears in GuideStar April, 2015.

by Bill Pellerin, GuideStar editor

Thuban Finder Chart

Object: Thuban
Class: Star
Magnitude: 3.7
R.A.:   14 h,  04 m,  23 s
Dec:   64 degrees,   22 minutes, 33 seconds
Distance:   309 ly
Constellation: Draco
Spectral:  A0
Optics needed:  Unaided eye, binoculars or a small telescope

Why this object is interesting:

This star is also known as Alpha Dra, even though it’s only the 7th brightest star in the constellation. Why? It’s not clear why, but the star has been and will again be the star closest to the projection of the north pole of the Earth.

It was in 2500 BC that the star Thuban was closest to the north pole. TheSky (software) puts it at approximately 1.5 degrees away from the pole. Polaris was 32 degrees from the pole. We all know that the Earth wobbles on its axis and completes a wobble cycle in 26,000 years. In another 2000 years or so Errai (Gamma Cep) in Cepheus will be our pole star...

New Members by Month

You may have wondered how I’ve been able to quote all the membership numbers each month to give you a clearer idea of who we are, or at least how many. A president has access, but it’s not total, and as for me, I rely on the knowledge and commitment of the committee chairs. So I get my numbers from Steve Fast, our membership chair and keeper of the member database.

Membership

For Steve, members are more than numbers, more than entries in a database. While he’s careful to keep your membership data accurate and your private information protected, he’s also the one who greets new members to the club with his informative welcome e-mail and gives us all a heads up when it’s time to renew (you did renew, didn’t you?). He’s also the friendly face at the membership table each meeting, the stellar star-hopper at the dark site ready to lend a hand, and past Field Trip & Observing chair who inspired successor Stephen Jones to take up the baton. I think of Steve as a friendly HAS ambassador. Many others know him as a helpful friend.

by the numbers

If you’ve been to the dark site a few times, you know Ed Fraini. Ed was one of the group who gave me my observatory training and helped me find Albireo in the 12.5” f/5 telescope. Sure I was intimidated, maybe fear is a better word. But what a rush when I found that colorful double star system myself. I’d long wondered who those guys were coming in and out of the observatory. Ed was one of them. Still is.

Some months ago I asked Ed to be part of the Long Range Planning committee to test a concept: Can we learn something about who we are, where we are, and where we’re going just by looking at the numbers? Steve fed Ed the data he needed, and Ed took that data—nothing personally identifiable—and went to work. At his presentation to the board in March, he showed us how much he was able to tease out. Concept proved, and the board has given him the green light to continue. I include one of his informative charts in this article...
