    No, it's not. Why don't you just try it out? Also, try the calculation using 27.24% (that's the value recommended in the Nautical Almanac --not that that's any reason to prefer it).

    You asked:
    "How "approximate" is "approximate?" "
    Exact enough for lunars. 'Approximate' only from the point of view of an astronomer.
    And you asked:
    " "0.14 minutes of arc." Off what standard, please?"
    The observed value of the Moon's diameter differed from the expected value of the Moon's diameter by 0.14 minutes of arc (which is a very small error --nothing to worry about).
    42.0N 87.7W, or 41.4N 72.1W.
