AbstractNew CCD photometric observations for asteroid (1028) Lydina, carried out with the 1-m and 2.4-m telescopes at Yunnan Observatory from 2011 December 19 to 2012 February 3, are presented. Using the new light curves, the rotation period of 11.680 +/- 0.001 hours is derived with the Phase Dispersion Minimization (PDM) method. In addition, using the Amplitude-Aspect method, the elementary results of the pole orientation of asteroid (1028) Lydina are obtained: lambda(p) = 111 degrees(+4 degrees)(-4 degrees), beta(p)=31 degrees(+4 degrees)(-5 degrees). Meanwhile, the axial ratios of the tri-axial ellipsoid are estimated: a/b = 1.77(-0:08)(+0.10) and b/c = 1.17(-0.09)(+0.07).
