Skygazers could get an Easter treat this Good Friday as spring's annual pink moon graces the night sky.
Despite its name, the April full moon, called the Sprouting Grass Moon, the Egg Moon, and the Fish Moon in other cultures, actually has no apparent colour change.
However, the term pink moon is a Northern Native American reference to an early-blooming wildflower, which starts to pop up in the US and Canada at the start of spring.
Like any full moon, this one should be visible in all its glory, fully illuminated by the sun.
Royal Museums Greenwich say the full moon will reach its peak little after noon, at 12.12pm, though it will be more visible after dusk.
The pink moon is particularly significant because it is used to set the date for Easter, which is the Sunday following the first full moon after the spring equinox.
