We present a glimpse of the kinematics of the Wolf-Rayet (WR) nebula G2.4+1.4 surrounding the subtype WO2 star WR 102. Here, we report the profiles of the lines [O III], Hα, [N II] and [He II] obtained through high-resolution spectroscopy from the OAN-SPM (Based on observations collected at the Observatorio Astronómico Nacional (OAN), operated in Mexico by UNAM). We found that the expansion velocities associated with those lines range from 15 to 25 km s^–1. The complex and filamentary structure of the source reveal that WR 102 is embedded into the interstellar medium, causing its peculiar shape.
