No, it’s *not* a “Blue Moon”

A blurb today at Newser announces that Friday will be a “Blue Moon.”

No, it won’t.

Summer began on June 20, and has only 3 full moons:

The next full moon won’t be until September 30, after the autumnal equinox. The next real Blue Moon will be August 21, 2013. But as Sky and Telescope noted, “With two decades of popular usage behind it, the second-full-Moon-in-a-month (mis)interpretation is like a genie that can’t be forced back into its bottle.”

The Old Wolf (and science) have spoken.
