It is a special case of the new moon. The fact that the Moon is between the Earth and the Sun on the day of the new moon does not mean that both the Earth, the Moon and the Sun are on the same line. The case of the Moon obscuring the Sun when all 3 are on the straight line creates a phenomenon of eclipse.

As a phenomenon occurs when the Earth, the Moon, the Sun is in line and the Moon is in the dark region of the Earth, it is not possible to receive light from the Sun.

Black Moon (Black Moon)

Is another special case of the new moon.

This is the opposite phenomenon of the phenomenon of black moon. In essence, the blue moon phenomenon implies this phenomenon is very rare and does not mean that the Moon is green.

The phenomenon of Super Moon occurs at the time of eclipse. At this point, the Moon enters the dark areas of the Earth and is obscured. However, light reflected from the Moon's surface is refracted when it passes through the Earth's atmosphere before the time of the total eclipse, causing the Moon to glow red like blood.
