  • What is it?

The rare lunar event happens when a supermoon, a blue moon and a blood moon happen at once.

The reddish colour is caused by sunlight getting refracted, or bent, towards the Moon, causing some blue light to be filtered out, leaving the red light which we can see.

It was the first time that all three lunar events happened at once since 1866.

The super blue blood moon appeared about 7% larger and 15% brighter than on a normal night.

There will not be another super blue blood moon until 2037.

Key definitions
