Dynamic and physical parameters of near-Earth asteroids from the observations.

We performed astrometric and multicolor photometric observations of near-Earth asteroids at the SBG telescope of the Kourovka Astronomical Observatory of the Ural Federal University and the Zeiss-1000 telescope of the Simeiz Observatory of the Institute of Astronomy of the Russian Academy of Sciences. We improved orbital elements and estimated the A 2 acceleration due to the Yarkovsky effect for asteroids (52768) 1998 OR2, (65690) 1991 DG, (159857) 2004 LJ1, (326732) 2003 HB6, (332446) 2008 AF4, (388945) 2008 TZ3, 2015 NU13 from astrometric observations with the SBG telescope. Furthermore, we estimated the axial rotation periods of the asteroids (137170) 1999 HF1, (159857) 2004 LJ1, (326732) 2003 HB6 from photometric observations with the SBG telescope. We obtained color indices for the asteroids (137170) 1999 HF1, (138127) 2000 EE14, (153591) 2001 SN263, (159857) 2004 LJ1, (326732) 2003 HB6, 2010 TV149 from multicolor photometric observations with the Zeiss-1000 telescope. Furthermore, we estimated the taxonomic classes for three asteroids, according to the color indices: the asteroid (153591) 2001 SN263 has class C, (159857) 2004 LJ1 has class S, and (326732) 2003 HB6 has class D.
