Just as the moon isn’t made of cheese, it isn’t really blue either, but on Friday the phrase, "once in a blue moon" will apply. August will end with the second full moon of the month.
The month of August started with a full moon, with the first one taking place on Aug. 1, and ends with the full moon Friday.
Modern folklore has dubbed the occurrence of two full moons in a month as a blue moon, according to the science website EarthSky.org. The blue moon happens only every two to three years. The next blue moon isn’t expected until July 2015.
The moon may be doubly blue Friday, because the funeral service for Neil Armstrong, the first man to walk on the moon, will be held Friday, according to Politico.
Armstrong died on Saturday at the age of 82. A private service is planned for Armstrong in Cincinnati, Politico reported.
And, while we may call it a blue moon, it is only a term and the moon is not really blue (or made of cheese) though sometimes conditions like smoke can make it appear blue-colored, according to EarthSky.org.
The National Weather Service says Friday it will be hot, with temperatures topping out at 95 degrees in Glen Ellyn. A slight chance of storms is possible, but those are likely after 1 a.m., so the sky should be clear for blue moon viewing.
