Night, moon high up in sky.
Moon between 12 and 18 degrees above horizon.
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.
Note that since it is a penumbral eclipse, it can be hard to see, as the Moon will only be a bit fainter.
