    SUMMARY: Astronomers from NASA think they know why large features on the surface of the Sun called supergranules rotate faster than the Sun itself. Thanks to data gathered by the Solar and Heliospheric Observatory (SOHO), the researchers believe it's actually just an optical illusion. In fact, activity is moving across the surface of the sun similar to what happens in a stadium when everybody does "the wave". Their next mystery, though, is to determine what causes this pattern of activity.

    Interesting! So it seems there is not differential rotation between the upper and lower regions of the sun.

    Hmm, I'm not sure that this can be concluded from the article, but if this is true would it have consequences for the idea on how the magnetic field is generated?

    Cheers.

    P.S. This article is 1 year old, (as Fraser explained these automatic updates (backdates really) happen once in awhile) but I hope the questions are still relevant.

    Usually a home run causes "the wave"
    Perhaps this is the result of some kind of celestrial home run.
