ASASSN-17jz is a luminous and slowly evolving optical transient discovered in the nuclear region of an active galaxy. It shows characteristics typical of both super-luminous Type IIn supernovae and active galactic nuclei (AGN) and it might be a new member of a small class of energetic events discovered in narrow line Seyfert I AGNs. Its slow evolution suggest the strong interaction between expanding ejecta and a very dense surrounding medium, perhaps the AGN accretion disk or torus. This is the first object in this rare class of transients with a detection at radio wavelengths. Here we propose ToO e-EVN observations of ASASSN-17jz to probe its radio morphology and radio emission at mas-scales to delve into the nature of this extraordinary transient.
