This Blue-supermoon won't happen again for another next 10years.

A "Super Blue Moon" is an even rarer occurrence than a regular Blue Moon. It happens when a Blue Moon coincides with a "supermoon." A supermoon is when the moon is at its closest point to Earth in its orbit, making it appear larger and brighter in the sky. So, a Super Blue Moon is a combination of a Blue Moon and a supermoon, resulting in a larger, brighter full moon that's quite spectacular to observe. This phenomenon captures the interest of skywatchers and photographers due to its visual impact and infrequent appearance.
