Last Supermoon of the Year/First Day of Spring/Vernal Equinox
It happens when a full moon coincides with the moment our satellite reaches its perigee, which is the closest point of its orbit to Earth.
There will also be several other supermoons throughout the year which will not be visible because they coincide with new moons when the surface of the moon cannot be seen from Earth. Tomorrow also marks the first day of spring. Things can only get better. 🎶🎶🎶
