The earths shadow is red, n so is the moon tonight
Blue moon is special because it is accompanied by an eclipse, an event that has not occurred in the last five to six decades. A lunar eclipse occurs whenever the moon passes through some portion of the earth’s shadow. This can occur only when the sun, earth and moon are aligned exactly or very closely aligned with earth in the middle. Lunar eclipse occurs only on a full moon day. “The full moon has to happen on the first or the second day of the month and the month must be of 31 days for such an event to occur. It has perfectly matched this month and hence the rarity.
