Photometric observations of six Mars-crossing asteroids with the 1-m INASAN telescope at Mt. Koshka

Abstract

. We present observations of six asteroids crossing the orbit of Mars obtained at Mt. Koshka observatory of INASAN in 2014–2016. Our multicolor photometry made it possible to determine the apparent magnitudes of asteroids in BVRcIc photometric bands, as well as their taxonomic class according to Tholen’s classification. The periods of rotation were determined for asteroids 9773, 32575, 97679, and 313591. For asteroid 8355 Masuo the rotation period determined earlier was confirmed. Our observations support the long period of rotation for asteroid 122463 (presumably about 19 days).
