TITLE: GCN CIRCULAR NUMBER: 41046 SUBJECT: EP250704a/GRB 250704B: 10 GHz VLA detection DATE: 25/07/09 04:57:07 GMT FROM: Roberto Ricci at INAF-IRA <ricci@ira.inaf.it> Roberto Ricci, Rosa L. Becerra, Eleonora Troja (Rome U.) report on behalf of the ERC BHianca team: We observed the field of GRB 250704B/EP250704a (Wang et al. GCN 40940; Li et al. GCN 40491) with the Jansky Very Large Array (VLA) at the center frequency of 10 GHz (with a bandwidth of 4 GHz) in C-array configuration on 2025 July 8th at mid observing time 07:53 UT (3.98 days after burst). A radio source was detected within the error circle of optical transient position (Schneider et al. GCN 40942) with a flux density of 92 +/- 7 microJy. This is consistent with the radio detection reported by Schroeder et al. GCN 41038. Further observations are planned. We thank the VLA staff for executing the observations.
