A massive supermoon — the first of 2015 — filled the skies last night as it reached its closest point to the Earth.

The so-called “supermoon” showed up beginning on Saturday evening and lasted into the early morning hours, getting to its closest approach to Earth at 222,631 miles away, which is known as perigee, according to a Baltimore Sun report.

This was an even bigger deal than usual perigees because it was accompanied by a full moon, which is why we call it a supermoon (not a technical term astronomically).

Not only that, with mostly clear skies on the East Coast, millions of people got a spectacular view of it in the United States.

This is the last full moon of summer, and it is called the Sturgeon Moon, which precedes the Harvest Moon, which marks the arrive of fall on Sept. 27.

The Harvest Moon may be the most dramatic full moon of the year, the Sun rights, as it will include a lunar eclipse that may result in another “Blood Moon,” as it glows a reddish color.

And during this period, the moon may appear huge to us: it will be even closer to Earth at just a little bit above 222,000 miles away, and then it will reach perigee on Sept. 28.

There will be yet another supermoon on Oct. 27, but it will be at a slightly greater distance.

Unlike solar eclipses, the moon doesn’t disappear from view — it simply starts glowing an eerie red color, earning its moniker of “blood moon.” It happens when the moon passes directly behind the Earth into its shadow.
