This is it, apparently. The last supermoon of 2019.

The super worm moon, is the last of 2019’s three supermoons and it will appear tonight when the moon becomes visible.

At 8:43 p.m. on March 20, the moon will officially reach its full phase. As a result of these combined events, the full lunar disk will appear 14 percent larger and 12 percent brighter than usual—a spectacle widely known as a supermoon.

The equinox supermoon will be the final one for 2019, which already saw supermoons fall on January 21 and February 19. But the year may have saved the best for last, given the coincidental timing with the March equinox at 4:58 p.m. on March 20th, less than four hours before the supermoon arrives.

The two celestial events won’t happen less than a day apart again until 2030. The next supermoon doesn’t come until February 9, 2020.
