GRB 210702A: MeerKAT radio detection
Abstract
"We observed GRB 210702A (Lien et al. GCN 30351) with the MeerKAT radio telescope array over two epochs beginning on 2021 July 11 12:16 UTC (8.7 d after the burst) and 2021 July 23 18:16 UTC (21.0 d after the burst), respectively. Preliminary analysis reveals a brightening radio counterpart with 1.284 GHz flux density of 123 +/- 12 uJy at 21.0 d at position: RA (J2000) = 11:14:18.76 Dec (J2000) = -36:44:49.5 with uncertainty ~ 0.4" in each coordinate, consistent with the X-ray position (D'Elia et al., GCN 30358), optical position (Lien et al., GCN 30351; Kuin et al., GCN 30356), and mm-band position (Laskar & Perley, GCN 30423). Further observations are planned. The MeerKAT telescope is operated by the South African Radio Astronomy Observatory, which is a facility of the National Research Foundation, an agency of the Department of Science and Innovation."
