    Lunars added to the Nautical Almanac app.
    All are free except Nautical Almanac.
    For your information Google Play gets the 30% of the sales. The money I get is donated to the Vicente Ferrer Foundation.

    Available on the app store:


    • Equatorial geocentric coordinates: RA/GHA, Declination for Sun, Moon, and navigational stars and planets . SHA.
    • SD, HP
    • SHA
    • Visible sky: identification of stars and planets - it plots the visible sky from a position. Polar & horizon chart
    • Planning observation: phenomena - Twilight, - Rise/set for Sun and Moon, - Meridian passage

        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.
