It’s only mid-March, but 2019 has already been quite the year for Super Moon enthusiasts, with several crazily named celestial events like the Super Snow Moon and Super Blood Wolf Moon. Tonight, stargazers in the northern hemisphere will be treated to a sight that is, according to the scientists who name these things, truly a once-in-a-lifetime event.

It’s called the Super Worm Moon, and before you ask, the answer is no — there won’t be hordes of giant, slithering annelids taking over our streets. The name does refer to worms, though, as they tend to emerge from the soil around this time of year. The “super” part refers to the fact that the moon happens to be full at the point in its orbit where it is closest to Earth, which will make tonight’s show quite easy to see for those of us blessed with a clear sky.

Making tonight’s Super Worm Moon even more special is the fact that it coincides with the spring equinox, which according to a report in The Guardian hasn’t taken place since 1905 and won’t happen again until 2144. It’s also the last Super Moon expected to appear in 2019.

The Super Worm Moon should be bright and obvious to any in Europe and North America. So if you’re in need of something to do tonight, grab those dusty binoculars off the closet shelf and park yourself in a lawn chair facing east. Luna promises not to disappoint.
