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.

Key words:
Very Long Baseline Interferometry (VLBI), Small Solar System Body (SSSB), hydro-silicate spots on asteroids, evidence of small body collisions, the spectral-frequency method (SFM), asteroid 21 Lutetia, asteroid 4 Vesta.
