Note: Someone brought a misspelling to my attention. I had originally mentioned "Gibbons Moon" when it should have been "Gibbous Moon." The source or sources I was using must have been incorrect. Apparently, I am not the only one having made that mistake. A thorough search on this matter has found my anonymous commenter correct. The word "gibbous" comes from Middle English meaning "bulging" from Late Latin, gibbosus, "humpbacked", from Latin gibbus, "hump." This post has been edited and the spelling corrected. Below are the phases of the moon in their entirety:
New Moon, Waxing Quarter or Crescent Moon, Waxing Half Moon, Waxing Gibbous Moon, Full Moon, Waning Gibbous Moon, Waning Half Moon, Waning Quarter or Crescent Moon, New Moon.
Hopefully this clears up any confusion! - Volker
