We report multiband observations of the Optical Transient ( OT ) associated with GRB000301c carried out between 2–4 March 2000 using the 2.34-m Vainu Bappu Telescope ( VBT ) at Kavalur , India .
When combined with other reported data , the initial decline in the R-band magnitude with log ( t - t _ { 0 } ) , the time since the burst is fit with a slope \alpha _ { 1 } = -0.70 \pm 0.07 which steepens after about 6.0 days to a slope of \alpha _ { 2 } = -2.44 \pm 0.29 .
This change in slope does not occur smoothly but there is an indication for a bimodal distribution .
The available measurements of the evolution of ( B–R ) color do not show any discernible evolution in the first 12 days .
