    I read this article earlier today. It is still slightly mysterious due to the star's lack of a strong magnetic field. 14% of the star's surface is a large spot for a star with a weak magnetic field.

    How weak is weak? The Sun has only a 1G magnetic field. This star's field is "less than 70 kG" so it is only less than 70,000 times the Sun's field.

    Good question. It would be nice to be able to compile data on various stars, their magnetic field, and average relative size of their starspots. As far as I know, we haven't developed the technology to resolve stars, other than our Sun, to that level.
