Although the total Lunar Eclipse on May 26, 2021, is a rather shallow one, it’s the only total lunar eclipse to occur in the year 2021.

On May 26, 2021, the full moon sweeps through the Earth’s dark umbral shadow to stage a short-lived total eclipse of the moon. Although totality lasts for less than 15 minutes, a partial umbral eclipse precedes and then follows totality by nearly 1 1/2 hours each time. So, from start to finish, the moon takes a little over three hours to cross the Earth’s dark shadow.
