The moon will reach its peak size tonight.

Since yesterday and into tomorrow, the moon will be especially large, especially bright, and especially beautiful. The “Worm” supermoon, a common March occurrence, began last night, March 8, will reach its peak size and brightness tonight, and will still be visible into tomorrow.

A supermoon occurs when a full moon cycle coincides with the moon’s perigee, which is when its orbit brings it closest to the Earth. The “Worm” moon got its name from old farmer’s almanacs because, when spring comes in March, the soil becomes soft and loamy thanks to worms coming out of hibernation. This also attracts the birds back to feed on the worms, so it’s a surefire sign that spring is upon us.

The Worm moon is estimated to be at least seven percent larger than the moon’s typical appearance, and is expected to be quite bright. It’s estimated that the moon will reach its peak at about 5:48 GMT today, though there should still be plenty of time to see it after that.

The Worm moon will be the last supermoon event for the winter, but there are several projected for the spring. A “Pink moon” is predicted to appear 221,851 miles away on April 8, and a “Flower moon” is predicted for May 7 at 224,429 miles away.
