| Abstract: | Asteroid 166 Rhodope moved at 14.4 milliarcsec/s during the occultation of Regulus of October 19, 2005. We made a 25 Hz frame rate video (resolution 0.6 mas per frame) near centerline in Vibo Valentia, Italy. Stellar and asteroidal diameters and relativistic light bending by solar field are outlined. The 0.16 mas differential effect of light bending (star-asteroid) is recovered fitting 7 observations with asteroid spherical model. | |
