Contact was taken in 2022 with MuSCAT2 team who uses the Carlos Sánchez Telescope, a telescope of 1.50 m diameter, almost fully dedicated to

C-complex asteroids are dark, low-albedo objects, mainly containing carbon components. Their spectra are usually featureless, especially in the visible-near-infrared (VNIR) wavelengths. However, for some taxonomic types, absorption has been found in the near-UV (NUV) range. Laboratory studies have shown similarities to spectra of chondrite
