Abstract
Six main belt asteroids 1999 HK1 (11411), 1995 AM1 (30968), 1999 XC136 (53454), 1999 JN6 (70055), 1999 UQ9 (86280), 2000 SU2 (93041) with Earth MOID less than 1AU were studied at the Baldone Astrophysical Observatory of the Institute of Astronomy of the University of Latvia in the time span range 2020-2022. The obtained light curve data together with published Minor Planet Center data in the time range 1999-2022 were analyzed with Fourier series, Lomb-Scargle periodogram, and Phase dispersion minimization methods. A plan of analysis step by step is given. The results computed from different observatories' data are compared and mean-weighted periods are obtained. The rotation periods are for asteroids: N11411 P = 6.544 h, N30968 P = 8.330 h, N53454 P = 4.615 h, N70055 P = 74.364 h, N86280 P = 1.315 or 6.658 h and N93041 P = 30.645 h.
