Moon between 6 and 12 degrees above horizon. Make sure you have free line of sight.

Moon between 0 and 6 degrees above horizon. May be hard to see due to brightness and line of sight.

Day, moon and eclipse both not visible.

Note: Twilight will affect the visibility of the eclipse, as well as weather.
