THE RESULTS OF PHOTOMETRIC RECORDING OF THE OCCULTATION OF THE STAR HIP 97157 BY ASTEROID (41) DAPHNE WITH THE TELESCOPE OF THE GLOBAL MASTER ROBOTIC NET

We have carried out photometric observations of the occultation of the star HIP 97157 by asteroid (41) Daphne on 2013 October 25 with the 40 cm telescope of the Global MASTER Robotic Net, located in the Tunka Valley near Irkutsk. We have obtained the photometric drift-scan of the occultation in broadband visible light. The photometric curve of the occultation of the star by asteroid Daphne was obtained. From analysis of this curve we have determined the length of the "chord" of the asteroid in the direction of its motion corresponding to the time interval during which the asteroid completely "screened" the star's light: a 146.86 ± 0.24 km. Also, assuming that the angular diameter of the star is equal to d 0002, we have determined the angles between the velocity vector of the asteroid and its two opposite edges (considered as straight lines) where the disappearance of the star and its reappearance occurred: for the front edge of the asteroid and for its opposite edge. So these edges of the asteroid are inclined toward each other at an angle of about 8°.
