A supermoon occurs when the moon reaches its closest position to the Earth, known as the perigee, making the satellite appear bigger and brighter than usual.
Its name is a northern Native American reference to an early-blooming wildflower called phlox subulata which are bright pink in colour and are first seen across North America as spring begins.
It was about 0.1 per cent closer to Earth than the March full moon was, making it the biggest supermoon of 2020, NASA reported.
April's full moon has also been known as the "sprouting grass moon" or "egg moon," heralding other first signs of spring.
Interestingly, the moon itself didn't look pink, but it appeared more golden as it rose above the horizon due to an effect caused by the planet's atmosphere, similar to how the sun appears more red as it rises and sets, according to NASA.
