Goedhart (SARAO) report on behalf\nof the ThunderKAT collaboration:\n\nWe observed the position of the GRB 190114C afterglow at 1.3 GHz with\nthe new MeerKAT radio telescope on January 15, from 18.25 to 20.74 UT,\ni.e. 0.94 days after the burst (GCN 23688). We detect a radio source at\nthe position of the afterglow. The afterglow flux is uncertain due to\nemission from the host galaxy, detected in a pre-GRB observation of the\nfield (MIGHTEE collaboration, private comm.). However, the flux level\nindicates significant synchrotron self-absorption in the GHz range (GCN\n23745). The two emission components will be disentangled with further\nanalysis and follow-up observations.\n\nWe would like to thank the staff at the South African Radio Astronomy\nObservatory (SARAO) for scheduling and obtaining these observations.",
