Abstract

The spatial distribution of granule sizes at the surface of the sun is investigated. Granules have been separated into two classes: those larger than 1″.37 and those smaller, where 1″.37 is the critical scale defined by Roudier and Muller (1986). It is found that granules are not distributed at random: large granules appear to be clustered, forming a cellular pattern with a characteristic scale of 7″; small granules form a similar and complementary pattern. These patterns are probably related to the mesogranulation.
