Alexander (Harvard) report on behalf of a larger\ncollaboration:\n\n\"The VLA observed GRB 171205A (D'Elia et al.; GCN 22177) at multiple\nfrequencies from 4.49 GHz to 16.38 GHz beginning on 2017 December 9.58 UT\n(4.3 days after the burst). At a mean frequency of 6 GHz, we detect a radio\nsource with a preliminary flux density of ~ 3 mJy at\n\nRA = 11:09:39.5182 +/- 0.0001\nDec = -12:35:18.480 +/- 0.002\n\nconsistent with the Swift/XRT position (Osborne et al.; GCN 22179) and the\noptical position (Izzo et al.; GCN 222180, Emery et al.; GCN 22181). The\nspectral index is steeply rising to higher frequencies as nu^2, suggesting\na self-absorbed spectrum. Follow-up observations are planned. We thank the\nVLA staff for rapidly scheduling and executing these service observations.\"",
