A list of asteroids is presented, observed frequently for color variations during rotation as an evidence for spots on the surface.+(−)sign means redder (bluer) at maximum brightness, < means no detection larger than scatter; lightcurve amplitudes are added, polarisation measurements and/ or other color indices are taken from reference 5. Out of a sample of 49 asteroids there is evidence now for ten objects to exhibit spotted Surfaces: 3 Juno, 4 Vesta, 6 Hebe, 25 Phocaea, 39 Laetitia, 42 Doris, 71 Niobe, 201 Penelope, 349 Dembowska and 944 Hidalgo.
