Pozanenko (IKI) report on behalf of larger collaboration:\n\nWe observed the afterglow of GRB080319B (Racusin et al. GCN 7427) with 0.7m \ntelescope of Institute of Astronomy, Kharkiv National Univ. starting on (UT) \nMarch 19, 18:20 and continuing to March 20, 02:44. The series consist of \ncontinuous observations in R and a few frames were taken in V around (UT) \n19:58.\n\nThe afterglow  (Racusin et al. GCN 7427, Holland et al. GCN 7428, Li et al. \nGCN 7430) is detected in the obtained single images.\n\nPreliminary photometry of combined images reveals a possible rapid decline \nof the light curve between (UT, mid time) 18:25 (R~19.1) and 19:04 (R~19.9) \nand then light curve flattering toward the end of observation March 20 (UT) \n02:00 (R~20.1). The light curve between (UT) 19:00 and 02:39 is close to a \nconstant and  not compatible with power law decay index of alpha=1.2.\n\nThe magnitude of the comparison star is based on SDSS calibration (Cool et \nal, GCN 7465).\nThe message may be cited.",
