What is the Apparent Magnitude of Rigel?

Google and Wikipedia list the apparent magnitude of Rigel, a bright star in the southeastern region of ORION the Hunter, as 0.12. However, EarthSky (reputable astronomy news source), WolframAlpha (scientific search engine), and various universities (including Florida St. University's Physics Dept.) say 0.18. Therefore, 0.18 may seem to be a more reputable answer.
