Troja (U Rome) on behalf of a larger collaboration:\n\nWe observed the short-duration GRB 250818B discovered by SVOM (GCN 41405) with Very Large Array in X-band at the centre frequency of 10 GHz with a bandwidth of 4 GHz on Aug 20th 2025, 2.3 days after the burst. \n\nAfter reducing the data in latest CASA version (v6.6.1) with standard procedures a detection was found at a position compatible with GOTO (GCN 41406) and NOT (GCN 41426) optical transient. We estimate a flux density of approximately 120 microJy. \n\nWe thank the VLA staff for promptly executing the observations. ",
