A statistical analysis of the intensity fluctuations of the solar photosphere, recorded photoelectrically, shows the influence of both seeing effects and especially the 5 min oscillations when intensity fluctuations at scales larger than the scale of the granulation are considered. A one-dimensional photo-electric set of records was time-averaged in order to show the existence of quasi-stationary cells in the range 5arcsec - 50arcsec, with amplitude modulations of up to ±30K. The photographic processing of a 23-min time sequence of excellent granulation pictures also showed the existence of cells of quasi-stationary intensity modulations. The amplitudes and stationary nature are larger for larger sizes, but the existence of cells at the meso-granulation scale is fully confirmed.
