Lunar Eclipse To Occur Overnight Thursday/Friday, March 13-14, 2025

An approaching weather system might block moon-gazers from watching a popular astronomical event.

A lunar eclipse will take place overnight Thursday into Friday (March 13th and 14th) as the Earth passes between the sun and the moon, which will cause the planet to cast its shadow on its orbiting satellite, turning it into a blood red color.

The penumbral portion of the eclipse will start at about 9:57pm on Thursday.

This is when the moon passes through the outer region of the Earth’s shadow.

Astronomers say a slight gray shade may appear on the moon’s surface, but it’s usually not noticeable.

The partial eclipse will start at about 11:09pm, when the moon starts to pass through the main portion of the Earth’s shadow.

During that time, the moon will darken and eventually appear as a blood red color to viewers.

At about 12:26am Friday, the moon will be fully eclipsed, and will stay that way until about 1:31am.

After that, the eclipse process will start to reverse itself.

The moon will be back in the penumbral phase at about 2:47am, and then be completely out of the Earth’s shadow at 4am.

Anyone wanting to watch the lunar eclipse in the Sheridan area could have a difficult time, because the National Weather Service in Billings, Montana is forecasting mostly cloudy skies during the event, with a 60% chance of rain and snow.

The next lunar eclipse will not be visible in Wyoming until March 3rd, 2026.
