T. Laskar (NRAO / UC Berkeley), K. Alexander, and E. Berger (Harvard)
report on behalf of a larger collaboration:

"We observed GRB 151027A (Maselli et al.; GCN 18478) at multiple
frequencies with the VLA beginning on 2015 October 27.95 UT (0.78 days
after the burst). At a mean frequency of 21.8 GHz, we detect a bright radio
source with a preliminary flux density of ~ 1.7 mJy at

RA = 18:09:56.691 +/- 0.001
Dec = 61:21:13.03 +/- 0.02

consistent with the enhanced Swift/XRT position (Goad et al.; GCN 18482)
and the optical position (Maselli et al.; GCN 18478, Zheng et al.; GCN
18479, Hentunen et al.; GCN 18503). Follow-up observations are planned. We
thank the VLA staff for rapidly scheduling these observations."
