Get ready for March’s full “Blood Worm Moon ,” a phenomenon that will make the moon appear red during a total lunar eclipse.
The full moon reaches peak illumination at 2:55 a.m. ET on Friday, March 14. The total lunar eclipse will make the moon appear red on Thursday, March 13 into the following day, depending on the time zone, according to NASA. This eclipse will be visible from Earth’s Western Hemisphere.
When and where to see the “Blood Worm Moon”
While this month’s full moon will rise early Friday, it will appear full from around Wednesday evening into Saturday morning, according to NASA. The Old Farmer’s Almanac details specific moonrise times for ZIP codes across the U.S. Local forecasts also include detailed information on how clear the night sky will be in various locations.
The “Blood Moon” phenomenon will start before the full moon reaches peak illumination. As the lunar eclipse begins, the moon will start moving through Earth’s shadow on Thursday night at 11:57 p.m. EDT. However, the moon’s gradual dimming won’t be noticeable until around 1:09 a.m. on Friday. The moon will be fully shaded from around 2:26 a.m. to 3:31 a.m., with the peak viewing opportunity for the red moon happening around 2:59 a.m.
