Pub. 249 Volume 1
You have Volumes 2 and 3 of Pub. 249 now. You may be curious as to what Volume 1 is about. It is designed to help a person take rapid star sights, and even suggest stars that are most visible in your latitude, and that provide a good "cut" with each other. We are not going to deal with Volume 1 in the class - it is enough to learn how to use Volumes 2 and 3. But you may be interested in taking a look at Volume 1, and playing around with it a bit. Volume 1 gradually goes out of date, and so it reissued every five years (volumes 2 and 3 are perennial). This is the edition issued in 2015 - and made available at no charge by the US Government. If you decide you like using Volume 1, I recommend waiting until the 2020 edition is published before you buy a hard copy of the book. This is a big PDF file, and can take a couple of minutes to load into your browser. If it fails, try right clicking on the link and using "Save Link As..." to do a direct download to your hard drive. |
