Forget about turning off the light that may be keeping you up on April 26-27. It’s streaming in through the windows from upstairs, outside. However, the source will have seemed larger earlier in the evening.
What’s shining through the windows if the sky is clear, is not merely a full moon. The orb outside is a Supermoon. It really isn’t larger. It just plays tricks on the eyes and perspective as it appears huge when first appearing at the horizon and in early evening.
The April full moon, also known as the “Pink Moon” is a Supermoon because it will be closer to Earth than most other full moons. The exception being the full moon in May 26, called the “Flower Moon” that will be even closer.
Some astronomy sites only designate the April and May full moons as Supermoons. Other sites include June 24’s which is also close. Still other sites include the March full moon which was fairly close.
For times to watch or photograph the moon check. EarthSky. The site also has the April, May June, 2021 Supermoons’ distances from the moon to Earth with April 27 at 222,212 miles (357,615 km), May 26 at 222,089 miles (357,462km) and June 24 at 224,662 miles (361,558 km).
If interested in how this all happens, you should know about the lunar perigee. It’s when the moon’s orbit brings it to its closest point to Earth. The opposite is apogee.
Of course, the third factor is where the earth is in relation to the moon and the sun to be a full moon. So, the April Supermoon actually happens about 12 hours short of it lunar perigee and May’s Supermoon falls about nine hours after perigee. The reason some sites refer just to April and May’s full moons as Supermoons is because less than 24 hours occur between the perigee and full moon phase.
Next, don’t be surprised if bothered with sinus trouble and have a full-moon sized headache. Because the pull of the full moon, particuclarly the Supermoon, does influence the tides, lore has it that their affect on humans and animals can also be felt.
