"We observed GRB 150811A (Evans et al; GCN 18119) at multiple frequencies
with the VLA beginning 2015 August 12.13 UT (0.96 days after the burst). At
a mean frequency of 21.8 GHz, we detect a radio source with a preliminary
flux density of ~ 0.1 mJy at

RA = 19:25:21.3920 +/- 0.0005
Dec = -15:25:31.00 +/- 0.01

consistent with the enhanced Swft/XRT position (Goad et al.; GCN 18124) and
the optical position (Butler et al., GCN 18120; Zheng at al., GCN 18121;
Kuin et al., GCN 18122). Follow-up observations are planned."
