Abstract

We have carried out observation, calculation and analysis of low-resolution reflectance spectra ($R\approx 100$) in the range of 0.35-0.92 $\mu$m of two near-Earth asteroids (93768, 68216), and four main-belt asteroids (2 Pallas, 787 Moskva, 11 Partenope, 245 Tercidina). Observations of the asteroids were performed using 2-m telescope with a CCD-spectrograph of INASAN Terskol Observatory to determine or specify their taxonomic types and estimate heterogeneity in composition at different rotational phases. Qualitative estimates of spectral (taxonomic) types of 787 Moskva and both NEAs are made.

Keywords:

asteroids, NEA, reflectance spectra, spectrometry, spectral type of asteroid
