Multiwavelength observations of the optical afterglow of GRB 050319 were performed from 1.31 to 9.92 hr after the burst. Our R-band light curves, combined with other published data, can be described by the smooth broken power-law function, with alpha(1) = -0.84 +/- 0.02 to alpha(2) = -0.48 +/- 0.03, 0.04 days after the gamma-ray burst. The optical light curves are characterized by shallow decays - as was also observed in the X-rays - which may have a similar origin, related to energy injection. However, our observations indicate that there is still a puzzle concerning the chromatic breaks in the R-band light curve (at 0.04 days) and the X-ray light curve (at 0.004 days) that remains to be solved.
