The linear thermal expansion coefficients a(T) of N2 - C60 solutions with 9.9% and 100% of the C60 lattice interstitials filled with N2 have been investigated in the interval 2.2 - 24 K. The dependence a(T) has a hysteresis suggesting co-existence of two types of orientational glasses in these solutions. The features of the glasses are compared. The characteristic times of phase transformations in the solutions and reorientation of C60 molecules have been estimated.
