Coherent elastic neutrino-nucleus scattering (CEvNS) is a fundamental process proposed more than 40 years ago but first observed in 2017 by the COHERENT collaboration. COHERENT deployed a suite of detectors at the SNS (ORNL, USA) to observe and study CEvNS on various nuclear targets. Argon nowadays is the lightest nuclear target which used for CEvNS research. CENNS-10 is a liquid argon scintillation detector located at 27 m from the SNS target. In this talk current status and first results of CENNS-10 science run will be presented.
