Observations of Mars-crossing asteroids with 1-m telescope of Simeiz Observatory of INASAN

Since 2010, multicolour observations of approaching Earth's orbit (NEA) asteroids have been carried out at the 1-m telescope in Simeiz. Not always, according to the observation conditions, it is possible to study the NEA of sufficient brightness to obtain high-quality observations, especially in multicolour photometry, when the camera response when using separate filters is too weak to obtain reliable information. In the absence of suitable objects from the NEA group, we selected objects of study from a group close to the NEA of the Mars crossover group. In some cases, these asteroids can also either cross the Earth's orbit or be close enough. Moreover, in the process of evolution of the orbits of NEAs and Mars-crossers, they can change belonging to a related family. Also very interesting is the opportunity to study the taxonomy of Mars crossers in comparison with the NEA and the characteristics of their own rotation, along with the evolution of their orbits. We present the results of observations of three Mars crossers observed with the 1-m telescope in Simeiz and an analysis of the data obtained on the rotation periods and characteristic features of the change in brightness and taxonomy.
