Hi all,

I just discovered this week that the US Naval Observatory's annual publication "Astronomical Phenomena" is now available free to download as a pdf. The 2015, 2016, and 2017 editions are now online. The booklet is a slimmed down version of the more comprehensive "Astronomical Almanac", the doyen of all you need to know (in tabular form) of what's happening in the sky each year.

Link is aa.usno.navy.mil/publications/docs/ap.php

Cheers Stephen!

I was doing some planning on the 2017 total solar eclipse in the US and stumbled across mention of the pdfs now being available. I used to purchase the Astronomical Almanac every year but it was getting very expensive. I now generate a lot of the tabular data through MICA, a software package (with book) published by Willmann-Bell in the US. MICA stands for Multi-year Interactive Computer Almanac.

Less rigorous tabular data can be created from the DOS-based FA (Floppy Almanac) which I believe is still downloadable and free or ICE (Interactive Computer Ephemeris) -- I'm not sure if the latter is free though. DosBox is a product to run DOS software under Windows 7 and it does the job brilliantly.

Thanks for the tip John, nice find! I have stickied this topic to make it easier to find also.

I see from your prep work that you have also added it to the IFAS 2016 Calendar an one of the many links to aid observing. ;-)
