Re: Sign of v correction to GHA

Here's a page and a half from "Nautical Astronomy" by Krasavstev and Khlyustin talking about that "foreign book" which, according to their text, they choose to refer to as the "Nautical Almanac". :) Note that this "Nautical Astronomy", which I do recommend, is fundamentally an English translation of an earlier Russian-language book from the Soviet era. It explains what's going on with the v corrections. It's all so clear after you read their explanation, isn't it? I'm kidding... I don't find it especially clear, but I thought I would throw it out there for you all to read.

These pages also highlight the fact that the US/UK Nautical Almanac does things in its own unique way. The authors appear to imply that the Soviet equivalent (which I have not seen) has nothing like this. The v correction is not an essential thing, and, in particular, it is not a property of the motions of the planets.

Sorry about the wobbly, out-of-focus photos. That's an indication of the limited value that we will get from these two pages. But again, I recommend this book and it's 600-odd remaining pages.

What is NavList?

NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

NavList is more than an online community... more about that another day.
