What does this data mean?
Civil Twilight: the time you can see things (under a clear sky) well enough to do activity outdoors.
Nautical Twilight: just about the earliest amount of time light can be seen on the horizon. The brightest stars with a clear sky can be seen, even though there is light on the horizon. This is good information for navigation and boating.
Transit: the time when the sun is directly overhead.
