Abstract
Calcium network diameters are shown to be smaller by 5% at solar maximum than at minimum. The average cell size at minimum is 22 115 ± 99 km. The average size at solar maximum is 20 920 ± 112 km, though individual maxima perform differently from each other depending probably on the dispersed remnant magnetic fields. The change in size of the network is interpreted in terms of changes in the size of the supergranular convective cell.
