Once-in-a-Blue-Moon

Full moon over Chilliwack isn't really a blue one

Clouds in front of the moon on Friday give it a dramatic appearance.

 

riday's full moon was referred to as a Blue Moon. It's called that because usually there are 12 Full Moon each year, or about one a month. Once in a while there are two Full Moons in the month and the second one is called a Blue Moon.

The term "Blue Moon" is thought to have originated back in 1883 when Krakatoa erupted and dust in the atmosphere made the moon and the sun look blue for two years.

The same thing happened in September 1950, when smoke from muskeg fires in Alberta spread across Canada and after Mt. St. Helen's erupted in 1980 and Mt Pinatubo in 1991.

The next Blue Moon won't be until July of 2015 and the last one showed up in March 30, 2010.
