Abstract

The spectral-frequency method (SFM) was developed in SAI and SRI CrAO [1]. It was used for investigations of sizes of hydro-silicate spots on the surfaces of asteroids 21 Lutetia and 4 Vesta. The results are in agreement with data from other observations. Spots are the result of small body collisions
