The Coma cluster is the richest and most compact of the nearby clusters, yet there is growing evidence that its formation is still on‐going. A sensitive probe of this evolution is the dynamics of intracluster stars, which are unbound from galaxies while the cluster forms, according to cosmological simulations. With a new multi‐slit imaging spectroscopy technique pioneered at Subaru and FOCAS, we can now detect and measure the radial velocities of intracluster planetary nebulae at 100 Mpc distance. The first results indicate that even the core of the Coma cluster is not well mixed.
