    The duration of the total eclipse is going to be about 4 minutes which is going to make it rather a unique experience.

      Fun fact: the Sun is 8.3 light-minutes away from Earth, so the eclipse will start with light that left the Sun 8 minutes earlier, and end with light that left it 4 minutes before the eclipse.

      If someone were to stand on Earth and send a signal to the Sun saying “hey, the eclipse is starting!”… it wouldn’t reach the Sun until 4 minutes after it already ended.

      (Edit: typo)

        Light is a constant and there isn’t gravitational lensing between the Earth and Sun. Any light from the Sun always reaches us at the same speed of roughly 8 minutes

          That’s what I said (minus a typo).

          (to nitpick however… there is some effect on the timing depending on how the planets align… wonder how a Moon right on its path impacted it)
