Abstract
The KM3NeT/ORCA is a next-generation neutrino detector currently under construction in the Mediterranean Sea. There are currently 6 Detection Units deployed, and in the past year the detector has been steadily taking data. Here the first neutrino oscillation measurement is presented using data taken with the ORCA detector 6 Detection Units, containing 354.6 days of exposure. Selection criteria are discussed, followed by a neutrino oscillation analysis. In the analysis it is found that oscillations are preferred with a confidence level of 5.9 $\sigma$ over "no oscillations". Likelihood scans of the $\Delta m_{31}^2$ and $\sin^2 \theta_{23}$ parameter also show a strong exclusion of the no oscillation hypothesis. The sensitivity contour in $(\sin^2\theta_{23}, \Delta m_{31}^2)$ is presented, showing results that are approaching to being being competitive with other experiments.
