supergranulation cell A convective cell, typically 15,000 to 30,000 km in diameter, in the solar photosphere that may last as long as a day. Supergranulation cells are distributed fairly uniformly over the solar disk. Their intersections are where most of the magnetic flux through the photosphere is concentrated and where new sunspots develop.
