Abstract:	We present the CCD Cousins R band photometric observations of the afterglow of GRB 041006. The multiband afterglow evolution is modelled using an underlying `hard' electron energy spectrum with a p1 ~ 1.3. The burst appears to be of very low energy (E ~ 1048 ergs) concerned to a narrow cone of opening angle theta ~ 2.3o The associated supernova is compared with SN1998bw and is found to be brighter
