Liimets  \n(NOT & Tartu Obs.)\nreport on behalf of a larger collaboration:\n\nWe observed the field of GRB 090529 (Sakamoto et al., GCN 9430) with  \nthe Nordic Optical Telescope equipped with MOSCA.\n3x600s R-band frames were obtained starting on May 30, 21:22 UT, 1.29  \ndays after the GRB.\n\nThe optical afterglow (Xin et al., GCN 9431; Schady et al., GCN 9435)  \nis well detected in our images. Using the same reference star as in  \nKann et al. (GCN 9436), we obtain R=22.5 for the afterglow.\n\nComparison with the measurement by Kann et al., taken 0.3 days after  \nthe GRB, provides a decay index alpha = 0.72, assuming a power-law F \n(t) propto t^-alpha.",
