On September 29th a new step in the building of the KM3NeT/ORCA detector in Toulon site was accomplished. After a long sea operation, the deployment and connection of the first node was performed. The first tests, made soon after the installation of the node on the seabed and under nominal high voltage, were successful. In the coming days and weeks the full commissioning of the system will be completed.
