Blue Moon lights up sky for stargazers; next will be in 2037!

2017nightsky2 Weekend Blue Moon Sighting Will Be Second Of 2018

Second Blue Moon of 2018 Arrives Saturday; It's the Last One Until 2020

The full moon coming tonight is also considered by some to be the Paschal Moon.

On 31 March, the inhabitants of the Earth will be able to observe the "blue moon" - the second in a calendar month the full moon.

When two full Moons occur in a single calendar month, the second full Moon is called a Blue Moon.

But there's more to the March Blue Moon than it just being the second full moon of the month.

An alternative name for March's full Moon is the Full Sap Moon, as this is the time of year when the sap of sugar maples starts to flow.

Great holiday weekend forecast; two weather-makers follow next week
Look for a sunny day today with highs climbing into the lower 70s - great weather for the first half of the Easter weekend . It's important to note, the further west and south you move from this cold front, precipitation type and impacts will vary.

Full Moon: March 1, 7:51 P.M. Though as the name suggest, the moon won't completely be blue. This is also the first full moon of Spring and as such it's designated as the Paschal Moon.

There are plenty of other factors that set the exact date of Easter, including Golden Numbers and when the Equinox falls, so the Paschal Moon is not an exact science. It's also sometimes known as the Worm Full Moon because it's the time when earthworms emerge from their winter slumber, according to the Old Farmer's Almanac. NASA says this particular event probably generated the phrase "Blue Moon," but volcanoes aren't the only reason a moon can look blue.

The moon does not actually turn blue, but the term "once in a blue moon" reflects a relatively infrequent event. Remember the Super Blue Blood Moon on January 31st? Consequently, both January and March ended up with two full moons, something that only tends to happen every 19 years or so.

Watch a livestream the blue moon rising on The Weather Channel app at 9:15 p.m. Friday. A large volcanic eruption (ash), or even wildfires (smoke, dust), can cause a reaction in the atmosphere that creates a bluish tinge. Due to the fact that it happened twice this year, we won't see the phenomenon again until 2020. The March Blue Moon has one more meaning that not many people may be familiar with.
