Figure 4: The development of prompt optical emission from GRB080319b as seen by TORTORA camera. Sums of 10 consecutive frames with 1.3 s effective exposures are shown for the gamma-ray trigger time (  s), the maximum brightness time during the first peak (  s), two middle-part moments (  s and  s), at the last peak (  s), and during early afterglow (  s) stages. Image size is degrees. The third and fourth images display deformed star profiles as during this time (since  s till REM robotic telescope (which has TORTORA camera mounted on top) repointed after receiving the burst information from Swift. Initially, burst position was on the edge of field of view, as a result of repointing it moved to the center of field of view, which resulted in better data quality.
