Today we will see a "Blue Moon"! Its a rare phenomenon when we have more than the general amount of full moons in a season. As it happens so infrequently, hence the expression about something happening "once in a blue moon".
Lunar activity is always compelling. Even though we have actually stepped on its surface, it still hold magic for us, with people recording its unusual or spectacular activity.
For example, on May 18, 1761, the moon was plunged into darkness for an hour and a half, in a deep total eclipse that showed the moon 45% of its diameter inside the Earth's shadow. Because of the Earth's atmosphere at the moment and evidence of volcanic eruption in the Indonesian Island of Halmahera, the moon looked red in color! You can imagine the fear and trepidation.
Nevertheless, as spooky as it might have been, it must also have been remarkable. So, don't forget to look up into the sky tonight. You may be able to see the Blue Moon!
