The full moon in April will be the largest and brightest of the year, appearing as the first of only two supermoons in 2021.
The rare spectacle occurs when the Moon approaches its closest point to Earth in its orbit, and the next one takes place almost exactly a month later on May 26.
The supermoon will reach its peak this month at 4.31 BST on April 27, but will appear full in the sky for casual observers every day on both sides.
The full moon in April is traditionally called the Pink Moon by Native American tribes and colonial settlers in the United States.
This is not because of its color – although it may look pink in certain circumstances ̵
This will be the first supermoon since May last year, when the moon passed 360,000 km (224,000 miles) from Earth. The full moon in April will pass only 357,378 km from Earth in its perigee.
The proximity of the moon must mean that it will be possible to see craters and other surface features, even without binoculars or a telescope.
The supermoon will appear even larger when it rises or sets above the horizon due to an effect called “Moon Illusion,” in which the eye is misled into comparing its size to objects in sight such as trees or buildings.
“Because these relatively close objects are in front of the moon, our brains are tricked into thinking that the moon is much closer to the objects in our field of vision,” said Mickey Adams, a solar scientist at the Marshall Space Flight Center. Nasa.
“When the moon rises or sets, it only looks bigger than when it is directly above the head, because there are no close objects to compare it to.”
Long-term weather forecasts from the Met Office suggest that the end of April will be a good opportunity for skagers in the UK to witness the pink supermoon.
The Meteorological Service predicts that “fine and dry weather is likely to be more common in general, especially in late April.”
