We present radio and optical afterglow observations of the TeV-bright long Gamma Ray Burst (GRB) 190114C, which was detected by the MAGIC telescope at a redshift of z=0.425. Our observations with ALMA, ATCA, and uGMRT were obtained by our low frequency observing campaign and range from ~1 to ~140 days after the burst and the optical observations were done with the 0.7-m GROWTH-India telescope up to ~25 days after the burst. Long term radio/mm observations reveal the complex nature of the… Expand
