The second Blue Moon of the year and the second full moon in March will rise this weekend ̵
The Full Sap Moon will rise at 8:37 am EDT (1237 GMT) on Saturday (March 31st). This full moon follows the full moon moon of March 1st and turns it into a Blue Moon – the name given to the second full moon, which is to occur in a single calendar month. But what makes this full moon special this weekend is that it will be the last Blue Moon until Halloween 2020.
The astronomy station Slooh will be hosting a live webcast on Saturday from 4pm. EDT (2000 GMT). You can also watch the webcast on Space.com courtesy of Slooh. [The Moon: 10 Surprising Lunar Facts]
The Blue Moon of Tomorrow is known as the Full Moon Moon because it marks the season in which the maple juice starts to flow and the annual tapping of the trees begins. Although the Moon will reach its fullness on March 31st at 8:36 am EDT, the observers will not be able to see the moon, as it will be below the horizon at this time.
Therefore, the best view is early morning at 7:03 am EDT, just before the moon goes down. However, the moon will look pretty full tomorrow at 19:37. SUMMER TIME.
The Full Sap Moon is not only the second full moon in March, but also the second blue moon of the year. (The first Blue Moon of 2018 was the spectacular "Super Blue Blood Moon" of January 31.) The occurrence of two Blue Moons in a row is actually a rare celestial event that astronomers call "Double Blue Moon," according to Slooh.
In fact, a double-blue moon is only seen about three to five times a century. The last time this event took place was in 1999, and the next Blue Double Moon will not be on display until 2037, Slooh officials said in a statement.
In general, a full moon occurs every month when the sun, earth, and moon line intersect with the earth. However, February did not have a full moon because it's a shorter month.
"The moon phase calendar takes 29.5 days to complete the cycle, which is why we have about one full moon per month," said Slooh representative in the statement. "But since some months are 30 or 31 days and February is shorter, we occasionally have a full moon-less February."
As a result, there are two full moons in March of this year – one of which is the Extraordinary Double Blue Moon this Saturday.
