Margutti (Northwestern), C. G.\nMundell (University of Bath), and P. Schady (University of Bath) report on\nbehalf of a larger collaboration:\n\nWe observed GRB 210610B (Page et al. GCN 30170) at a mean frequency of 14.7\nGHz with the Karl G. Jansky Very Large Array (VLA; Program 21A-241)\nbeginning 2021 June 11.22 UT (9.4 hours after the burst). We detect a radio\nsource with a preliminary flux density of ~0.25 mJy at:\n\nRA (J2000) = 16:15:40.381\nDec (J2000) = +14:23:56.59\n\nwith an uncertainty of 0.07 arcsec in each coordinate. This position is\nfully consistent with the optical afterglow (Page et al. GCN 30170; Kumar\net al. GCN 30174) and the refined Swift/XRT afterglow position (Osborne et\nal. GCN 30189). Additional follow-up observations are planned.\n\nWe thank the VLA staff for rapidly approving and executing these\nobservations.",
