T. Laskar, A. Zauderer, and E. Berger (Harvard) report:

"We observed the position of GRB 121024A (Pagani et al; GCN 13886) with the
EVLA beginning on 2012 Oct 25.3 UT (1.2 days after the burst). At a mean
frequency of 22 GHz, we detect a radio counterpart with a preliminary flux
density of ~ 0.1 mJy consistent with the enhanced Swft/XRT position
(Osborne et al; GCN 13894), the optical position (e.g. Knust et al.; GCN
13891) and the CARMA 3 mm position (Zauderer et al; GCN 13900). Follow-up
observations are planned."
