    Re: Confidence in Moonsights

    >>it took an extraordinay long time to produce Moon Ephemeris theories accurate to +/- 6" . 

    >>..."theories" whether analytical or numerical integrations

    I have struggled with this whole concept.  It seems like the moon's orbit, as one of the class called "the three-body problem" may be chaotic:  fundamentally unpredictable.  But then I read other things that suggest we can predict the moon's orbit with enormous accuracy centuries into the future.

    I lack the math background to understand the phrases "analytical integrations" and "numerical integrations".  I look forward to the discussion here.

    I have observed reduced accuracy in my own moon sights...but when I did, I always assumed that the moon's illuminated limb didn't QUITE wrap around to the exact bottom for a lower limb observation, or to the exact top for an upper limb.
