Ok, Say the Sun has set, and it is now 1 degree below the horizon. How high would you have to get, to be able to see the sun again?
Now you have that basic thought. Now lets go a slightly different way.
OK the sun is not a point source but is about 1/2 a degree in size. So to have the Sun be fully set below the horizon, the center actually has to be 1/4 degree below the horizon.
Now what I want to learn is say for every 10,000 feet in altitude,
10,000
20,000
30,000
etc.
say at 10,000 feet the center of the Sun has to be how many degrees below the horizon, so it has all barely set and is not visible anymore?
