TITLE: GCN CIRCULAR NUMBER: 30542 SUBJECT: GRB 210726A: 6 GHz VLA radio upper limit DATE: 21/07/28 22:38:02 GMT FROM: Genevieve Schroeder at Northwestern University G. Schroeder, W. Fong, A. Rouco Escorial, (Northwestern), T. Laskar (U. of Bath), E. Berger (Harvard) report: "We observed the position of short GRB 210726A (Bernardini et al., GCN 30523; Veres et al., GCN 30540; Palmer et al., GCN 30536; Tohuvavohu et al., GCN 30535) with the Karl G. Jansky Very Large Array (VLA) under program 20B-057 (PI: Fong) beginning on 2021 July 27.81 UT (1.00 days post-burst) at a mean frequency of 6 GHz. Based on preliminary analysis, in 1 hour of observations we do not detect any radio emission at or near the position of the XRT afterglow (Osborne et al., GCN 30524) to a 3-sigma limit of 15 microJy. Additional, detailed analysis is ongoing. We thank the VLA staff for quickly approving and executing these observations."
