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 entire eclipse is visible from start to end.

The entire partial and total phases are visible. Misses part of penumbral phase.

The entire total phase is visible. Misses part of partial & penumbral phases.

Some of the total phase is visible. Misses part of total, partial & penumbral phases.

Some of the partial phase is visible. Misses total phase and part of partial & penumbral phases.

Some of the penumbral phase is visible. Misses total & partial phases.

The eclipse is not visible at all.

Note: Areas with lighter shadings left (West) of the center will experience the eclipse after moonrise/sunset. Areas with lighter shadings right (East) of the center will experience the eclipse until moonset/sunrise. Actual eclipse visibility depends on weather conditions and line of sight to the Moon.
