Why Polaris isn't listed?

[Rumata]

Rumata,

I can't exactly answer your question.  However, while Polaris is easily found in the sky, Pub. 249 Vol 1 includes the Polaris tables 6 & 7 on page 353 (the last page of tha volume).

The Air Almanac also includes the Polaris tables and can be found here-

Polaris- Correction for (Q) (2017)

I think that version is included on the TheNauticalAlmanac.com since it's the most up to date version though the one found in Pub. 249 Vol. 1 will not yield a significantly different result.

Polaris is typically used just to determine latitude.  Using the Polaris Tables 6 & 7 only require LHA ♈ (Aries) and not the additional SHA of Polaris to solve for latitude.  Thus, you can determine latitude quickly using Tables 6 & 7 than the lengthy process of using Polaris's SHA and drawing an LOP.

While Polaris is a useful, my guess it's not listed in the Pub. 249 Vol. 1 stars as it's not very bright.  But there could be other considerations that I'm not familiar with.

The Nautical Almanacs found on TheNauticalAlmanac.com provide Polaris's SHA & DEC for each year on the daily pages.

You can get the procedure to determine latitude using Polaris here- Determine Latitude using Polaris

Polaris also has the Latin name of a Ursae Minoris

You can also get the principle navigational stars SHA & DEC from the Air Almanac here-

Thank you, Clen. I know about the tables which are used to determine the latitude by Polaris. And yes, I think you're right, Polaris isn't the brightest one in the sky. As I've mentioned, I worked on some intercept problems and the input included Polaris among other stars. Then, by accident I found out that even in Nautical Almanac 2005 for instance, which doesn't list Polaris SHA per se, on page 272 it does includes it as alpha Urse Minor ( surprise ;>) and gives it SHA and declination. But you really need to search for it to find it out.  Not in the middle of nowhere, for sure.

Anyway, thank you again for the response.
