Abstract: In order to make a meaningful comparison between the absolute magnitude calibration for O stars in the Milky Way and the Magellanic Clouds, a reexamination has begun of the sources of data for this calibration of Galactic O stars. The large mean error in the Galactic O star absolute magnitude calibration is of considerable concern. From a preliminary study of the earliest O stars, it appears that this error is not due to the inclusion of poor quality data. A comparison among Galactic and Magellanic Cloud data sets is presented.
