SUBJECT: GRB 140516A: 6 GHz upper limit

W. Fong, B. A. Zauderer and E. Berger (Harvard) report:

"We observed the field of the short-duration GRB 140516A (Bernardini et
al., GCN 16285) with the Karl G. Jansky Very Large Array (VLA) beginning on
2014 May 17.48 UT (14.94 hr post-burst) at a mean frequency of 6 GHz. In 1
hour of observations, we do not detect any radio source in or around the
enhanced XRT position (Osborne et al., GCN 16289). We therefore place a
3-sigma limit of 24 microJy on the radio afterglow of GRB 140516A at 14.94
hr after the burst.

We thank the VLA staff for quickly executing these observations."
