Which one of the following statements is correct regarding the Super Blue Moon? |ForumIAS

[A] It is a rare celestial event where a full moon is both a supermoon and the second full moon in a calendar month.

[B] It is a rare event when two full moons occur in a single month and the second moon is slightly farther from Earth, making it appear smaller.

[C] It is a phenomenon where the moon is closer to Earth and appears blue in colour due to scattering of light in the atmosphere.

[D] It is a full moon that coincides with a lunar eclipse causing it to appear blue.

Answer: A

Notes:

Explanation –

Supermoon: This occurs when the full moon is at its closest point to Earth in its elliptical orbit, known as perigee. This proximity makes the moon appear larger and brighter than usual in the night sky.
Blue Moon: This term traditionally refers to the second full moon within a single calendar month. Since the lunar cycle is about 29.5 days, occasionally two full moons can fit into one month, making the second one a “blue moon.” The term “blue moon” does not refer to the colour of the moon.
Super Blue Moon: When these two phenomena coincide—meaning the second full moon of the month is also a supermoon—it results in what is called a Super Blue Moon. This is a rare event, occurring roughly once every 10 years, offering a spectacular view as the moon appears both larger and brighter.
