Solanki &amp; Montavon proposed an "uncombed" model in which a part of these structures consists of embedded flux tubes in a homogenous background. Redshift at the limbside and blueshift in the centerside of these objects are explained by Evershed flow of gas across them. Coriolis force is thought to explain the fact that the tilt angle between the leading and (*) following of these objects increases with increasing latitude, and they get flatter as they approach the limb. Groups of the delta class of these objects are strong emitters of H-alpha. George Hale used spectral Zeeman splitting to estimate that the magnetic fields in these objects is 2600 to 2900 gauss. The creation of these entities is maximal when the a certain magnetic flips polarity; that event occurs every eleven years. Solar flares often originate near, for 10 points, what dark regions on the sun?
