A rare cosmic phenomenon will occur in the skies at the end of September, as the full moon will be exceptionally near the Earth on one night, but at 3 a.m., the Earth will stand between the moon and the sun.

A Supermoon takes place when a full moon or a new moon occurs while the moon is in a closer position to the Earth. The moon shines brighter in this situation. As both the moon and the Earth produce gravity, gravitational forces are stronger during the Supermoon, Earthsky reported. 

The occurrence may trigger high tides and volcanic eruptions, according to The Independent.

A Blood Moon is also called a total lunar eclipse, and only three to five of these happen in a decade. The lunar tetrad occurs when the Earth finds itself between the moon and the sun. The moon does not disappear, but it will look red. Blood Moons are associated with witches, werewolves, and other grim events in myths and traditional stories, Time and Date reported. Because September's Blood Moon coincides with the Feast of the Tabernacle, apocalyptic predictions are going around.

The lunar display on Sept. 28 will be extraordinary because a Supermoon and a Blood Moon will happen on the same night.

The end of September is also a period of Equinox, the time between seasons in which the sun and moon pull equally on the oceans. Unusual weather patterns and higher tides occur during the Equinox.

Because Supermoon, Blood Moon, and equinoctial tides will occur on the same night, some people are worried that it will be the end of the world.  

There's a good chance that the high tides will occur, according to the U.K. National Tidal and Sea Level. They will be only an inch or two higher than the highest tides of the last 20 years.
