    Re: Sun sights during an eclipse: "bad limb" calculation
    From: Geoff Hitchcox

    Hi Kermit,

    You asked if I could give the data for the 1st touch, well thanks to Chuck_V he has already saved me the trouble by giving first and last touch details here. Many thanks for doing that Chuck, you have provided a much better layout than I would have.

    However, I did modify my code to give the *speed* between Moon and Sun centers at each 0.5 second sampling.

    First touch = +0.34 arc"/time" (the *same* for both Airless and Refractive models).

    Last touch = -0.30 arc"/time"  (the *same* for both Airless and Refractive models).

    Positive meaning the centers were moving towards each other.

    Negative meaning the centers were moving away from each other.

    Note: Because the location (28N,-90E) was not on the central path of the Annular Eclipse, the respective centers of the Moon and Sun were never congruent. It was a diagonal glancing track of the Moon over the Sun.

    Hope that helps Kermit.

    Regards, Geoff Hitchcox, Christchurch, New Zealand.
