These assist in determining the heliographic latitude and longitude of sunspots.
In other chapters information of interest to only the most dedicated enthusiasts--such as the mathematical technique for determining the heliographic latitude and longitude of a sunspot--is belabored in the main text.
They resemble polar plumes, though some are located at quite low heliographic latitudes. Indeed, they are polar plumes, as long as we're talking about the magnetic poles, not the rotational ones, for they emanate from opposite ends of the equivalent dipole (arrow).
