Shades of darkness
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.

The raw data is based on population estimates from the year 2000 to 2020.
An Eclipse Never Comes Alone!
A solar eclipse always occurs about two weeks before or after a lunar eclipse.
Usually, there are two eclipses in a row, but other times, there are three during the same eclipse season.
This is the first eclipse this season.
