"We observed GRB 221009A (Dichiara et al. GCN 32632) with the MeerKAT radio
telescope array beginning on 2022 October 10 19:10 UTC (1.3 d after the
burst). Preliminary analysis reveals a radio counterpart with 1.284 GHz
flux density of ~ 2.1 mJy at position:

RA (J2000) = 19:13:03.47 +/- 0.04"
Dec (J2000) = 19:46:25.08 +/- 0.06"

This position is consistent with the optical position (Dichiara et al., GCN
32632; Lipunov et al., GCN 32634). 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."
