β¦ Synopsis
Small chromospheric emission centres (here defined as floceuli) were studied photometrically on Kz.3,z spectroheliograms taken at the Arcetri Observatory. The intensity ratio between hi, the ftocculus brighteess, and Ionr, the brightness of the chromospheric background, was determined. A difference was found between the polar and the equatorial limb values of the ratio hi/Ichr.
