What is a 'full worm moon'?

The supermoon comes a day after the moon reaches perigee, the closest point to Earth, making the full moon a supermoon, which makes it appear slightly about 10 percent larger than the full moon usually does.

In New Jersey, New York City and Philadelphia, the National Weather Service is calling for mostly clear to partly cloudy skies Tuesday night and mostly cloudy skies Wednesday night, when rain showers are expected to approach the region.

This time of year, the sun stays up about 2½ minutes longer each day here, helping to gradually warm temperatures throughout spring. It will be the first time in almost 40 years that the full moon has coincided so closely with the vernal equinox, according to The Old Farmer's Almanac.

It is rare that the full moon coincides so closely with the equinox, according to EarthSky.org. Unfortunately, local sky observers seem likely to face increasing clouds by late Wednesday. However, for those who couldn't get enough of February's "super snow moon" or January's "super blood wolf moon" eclipse, the "super worm moon" will be the last opportunity for a while to see a supermoon.

The upcoming supermoon will coincide with the spring equinox, which marks the official beginning of spring. According to the Old Farmer's Almanac, the moon will appear bigger and brighter than usual.

If you're in the United Kingdom, the moon will be at its brightest at around 1.43am on Thursday, March 21. The asteroid, called 2019 EA2, will be even closer to Earth than the moon, according to the Minor Planet Center .
