    Silicon Beach Proposal

    Silicon Beach Proposal
    Apparently other basic learner CN students followed the AP/DR/EP discussion
    with considerable interest.  One emailed me off list to ask for my Carribean
    sight data so that he could practice working them up.  I am also looking for
    free sight data to work up in practice for my exams.
    So following Dan Hogan's fine "Silicon Sea" tradition, I am working on a
    more basic website section called "Silicon Beach", intended to complement
    Silicon Sea.  My plan is to post really basic sight data for learners to
    work up.  The URL is
    http://jimthompson.net/boating/CelestialNav/SiliconBeach/SiliconBeach.htm .
    Many of us have to practice sight-taking from the shore, hence the name
    "Beach".  (It is also named after the tropical place that I took those 150
    sights from a couple of weeks ago, and cannot get out of my mind.)
    Silicon Beach will differ from Silicon Sea in that we'll post unrelated
    examples of very basic sights.
    - Silicon Beach will not be "real time", and the sights will not be part of
    a cruise.
    - SB will include sights from a shoreline or anchored vessel, typical for
    the early experience of many CN students.
    - We want to find sights for both hemispheres, and from both East and West
    of Greenwich.
    - However SB will also include sights taken from a moving vessel, if I can
    get some from somebody (Doug?).
    - Maybe eventually we can build a small practice cruise too, using a linked
    series of sights.
    Please feel free to send me some problems to post on the Beach.
    I think we are looking for the following categories of simple sights:
    - Simple LAN sights.
    - Polaris sights.
    - Basic twilight 3-body fix, morning and afternoon.
    - Morning and afteroon sun sights.
    - Run of 5 sights on the same rising or setting body, to practice getting an
    - UL and LL moon sights.
    - Planet sights, especially Venus.
    I like the idea of including some supplementary questions with wrinkles
    like, "Can you determine longitude from this LAN sight?", or "What would Zn
    be if the latitude was S instead of N?" so if your sight includes those
    possibilities, then send me those questions too.
