Astronomical Almanac 2013
      #5359010 - 08/09/12 12:09 AM

For those of you so inclined, this book is now available from the U.S. Govt. Printing Office. $40 delivered. If you wait until the end of the year, they'll be out of them. I buy one every year. I don't use it very often; but I love having the information handy when I do need it.

Rick,

This might also be of some interest to you and others. The new hardcover edition of "Explanatory Supplement To The Astronomical Almanac". Always wanted to buy one of these but wasn't sure if it would be helpful to an amateur astronomer without much mathematical background.

Probably not. But for those of us who are reasonably fluent in math, it's priceless.

Tony,

Would you explain? I'm not familiar with the "Supplement". I've always used the Almanac just for accurate positions of objects, mostly planets. What's in the Supplement that makes it valuable to the math-literate?

The supplement explains the algorithms that are used to derive the data in the Almanac -- for instance, the brightnesses of the planets, which are inevitably estimates at best. That's useful if you're interested in algorithms and/or want to understand the limitations of the data in the Almanac.

Tony, thank you for your valuable advise. I think I will go ahead and buy it. I have had high school level mathematics and I am teaching myself calculus etc. Hopefully, I will find it useful.

Thanks for the heads-up. I often don't think to order a copy until the end of the year, and in 2011 I ran into the sold out scenario you mention and had to wait 2 months into the new year before getting it. I find these to be an indispensable reference when preparing our monthly newsletter.

I have already placed an order for the Astronomical Almanac for 2013 and it should arrive in a few days. I am also waiting for the "Explanatory Supplement To The Astronomical Almanac" but that is a long wait.

I got my Astronomical Almanac for the year 2013 today via postal mail. I was going through the tables and I find that dates given for all the planets, also includes December 32nd. Are we going to have 32 days in the month of December in 2013? Are there any changes to the calender in offing?

The AA also includes January 0. Very useful for interpolation.

It doesn't much matter, what with the world ending on 12/21 and all.

December 21st?

I thought it ended on November 6th this year.

What can this book give me that the "Observer's Handbook" from RASC - or Sky Safari Plus - can't?

Thanks, Ira. I put the website in my Favorites. I think that's about as far as I'll go with this item.

Not much, probably. It's much more detailed than the RASC Handbook, but you probably don't need or care about that level of detail. And a good planetarium program like Sky Safari Plus can generate much if not most of the data in the AA.

Those of us who write planetarium programs need the AA to check their accuracy!

Yes, please do check the AA so we can have accurate planetarium programs!
