Though it didn't actually appear blue -- far from it, in fact -- the full moon setting this morning drew a lot of attention from the media and residents simply because of its catchy nickname.

The second full moon of the month, called a blue moon, was visible overnight, though the official time of it reaching its full phase wasn't until 9:58 this morning after it had set in Pittsburgh.

Because the moon orbits Earth once about every 29 days, it's possible for two full moons to occur in a calendar month. The last full moon was Aug. 1.

Next month's full moon also has a catchy nickname. When it reaches full at 11:19 p.m. Sept. 29, we'll be seeing the harvest moon.

And the next blue moon? Not until 6:43 a.m. July 31, 2015.
