There are five phases to be aware of, each with something special to offer:

The opening partial eclipse phase

The onset of totality

Totality

The end of totality

The closing partial eclipse phase

The opening and closing partial eclipse phases are fun, providing sublime views of the Moon moving across the Sun. It’s during this phase that eclipse glasses must be worn to avoid serious and permanent eye damage. Cameras and telescopes must also be protected with solar filters during these opening and closing phases.
