    We are discussing about the eclipse, but are flat Earth even seeing this? Even if they are seeing this I certainly believe their beliefs and "truth story" will still stay but let us just hope that I am wrong about this. Whatever the thing is, I have gained a lot of knowledge about our place in the universe and have learned about different people and their hard attitude and denial.

    They tend to see what they want to see. I guess that's true for most of us, to varying degrees. But moreso for some. ;)

    About science I will always believe what evidence will say, even if it will go against my beliefs that I have held for years, because SCIENCE IS THE TRUTH!!! Although I do come up with with my on philosophies regarding metaphysics, like is their any purpose of why we are here? What is beyond our understanding that transcends time and space? What is love, and how it descends in our thoughts, a classical example would be from Interstellar when Dr. Brand describes love and its meaning to Cooper.

    That's awesome. I tried to get earthshine but my long exposure shots had too much internally reflected light in the telescope from the bright corona. Drat.

    You can kind of see how some of the features very faintly show up, but the scope has a characteristic blue internal reflection I've seen before with bright stars, and the corona produced it as well.

    Anyway, just to add my two cents, I did the math on the approximate path of the moon's shadow across the earth's surface, by first calculating the coordinates the shadow is projected out into space as being 180 degrees from the sun's position relative to the center of the moon. I then calculated the position of the earth's center relative to the center of the moon, and finally, the angular separation and position angle of the shadow's coordinates relative to the earth's coordinates as seen from the center of the moon. Using that information I calculated the shadow's latitude and longitude on earth by calculating the latitude and longitude of the sub lunar point and the following formulae:

    Latitude = arcsin(Sin(Moon Latitude)*cos(p)+cos(Moon Latitude)*sin(p)*cos(-theta))
    where Moon Latitude = Latitude of the sub lunar point
    p = arcsin(d/angular size of earth from moon)-d
    where d = the angular displacement of moon's shadow from center of earth as seen from the center of the moon
    theta = position angle of the displacement of the moon's shadow, with 0 degrees at north.
    Longitude = arcsin((sin(p)*sin(-theta))/cos(latitude))-moon longitude
    where moon longitude = Longitude of the sub lunar point
    latitude = latitude of the moon's shadow calculated in the first equation.

    The equations I used assumed a spherical earth, which isn't exactly true, but the result is close enough to demonstrate the general west-to-east path of the moon's shadow across the earth during the eclipse. Actually given my approximation I was pleasantly surprised by how close the resulting path was to the true path:

  5. Great thread, I learned some cool stuff about how the moon travels I forgot or never knew. Been lurking for a few catching up on old threads.
