TITLE: GCN CIRCULAR NUMBER: 45065 SUBJECT: GRB 260610B: VLA detection DATE: 26/07/02 20:07:05 GMT FROM: Tanmoy Laskar at U of Utah <tanmoylaskar@gmail.com> T. Laskar (Utah), B. P. Gompertz (Birmingham), G. E. Anderson (Curtin), A. Levan (Radboud and Warwick), Daniele Malesani (DAWN/NBI and Radboud), Steve Schulze (Weizmann), Nial Tanvir (Leicester), A. J. van der Horst (GWU) report on behalf of a larger collaboration: “We observed GRB 260610B (Fermi GBM team, GCN 44891; O'Neill et al., GCN 44903) with the Karl G. Jansky Very Large Array (VLA) at multiple frequencies beginning on 2026 June 13 at 07:23 UT (2.89 days after the burst). In preliminary analysis, we detect the radio counterpart (Laskar et al., GCN 44941) at 9 GHz with a flux density of ~ 0.4mJy at the position: RA(J2000) = 14:32:38.25 +/- 0.01” Dec(J2000) = 27:00:17.64 +/- 0.01” This is consistent with the optical position (O'Neill et al., GCN 44903) and radio position (Laskar et al., GCN 44941). Further observations are planned. We thank the VLA staff for scheduling and executing these observations.” View this GCN Circular online at https://gcn.nasa.gov/circulars/45065. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0LW...
