Super Blue Moon: When is it and how Arizonans can watch the astronomical phenomenon

Phoenix, Arizona: Arizonans can experience a rare super blue moon on Monday. This year’s first supermoon is also a seasonal blue moon and a rare third full moon in an astronomical season.

The moon will rise in Arizona at 7.31pm on Monday and reach its highest point early on Tuesday morning at 12.43am. The moon will rise in the eastern to southeastern skies, gradually climbing to about 44 degrees above the horizon by midnight. 

What is a supermoon?

A supermoon is a full moon or a new moon that appears larger and brighter than usual because it occurs when the moon is at its closest point to Earth in its orbit, known as perigee. 

Perigee: The moon's elliptical orbit brings it closer to Earth at perigee, making the moon appear up to 14% larger and 30% brighter than when it is at its farthest point (apogee).

Frequency: Supermoons typically occur a few times a year.

Visual Impact: While the difference in size and brightness is noticeable, it might not be dramatically apparent to casual observers compared to a regular full moon.

Are Blue Moons really blue?

Despite the name, a blue moon does not actually appear blue. The term "blue" has no relation to the moon's color. However, atmospheric conditions, such as volcanic eruptions or large wildfires, can sometimes cause the moon to appear bluish, but this is unrelated to the blue moon phenomenon.
