AbstractWe present photometric and spectroscopic observations of the type Ibn supernova (SN) 2019uo, the second ever SN.Ibn with flash ionization (He II, C III, N III) features in its early spectra. SN.2019uo displays a rapid post-peak luminosity decline of 0.1 mag day(-1) similar to most of the SNe.Ibn, but is fainter (M-max(V) = - 18.30 +/- 0.24 max mag) than a typical SN.Ibn and shows a color evolution that places it between SNe.Ib and the most extreme SNe Ibn. SN.2019uo shows P-cygni He I features in the early spectra which gradually evolve and become emission dominated post peak. It also shows faster evolution in line velocities as compared to most other members of the type Ibn subclass. The bolometric light curve is fairly well described by a Ni-56 + circumstellar interaction model.
