We report on the discovery of AT2018lqh (ZTF18abfzgpl) – a rapidly-evolving extra-galactic transient in a star-forming host at 242Mpc. The transient g-band light curve’s duration above halfmaximum light is about 2.1 days, where 0.4/1.7 days are spent on the rise/decay, respectively. The estimated bolometric light curve of this object peaked at about 7× 10 erg s – roughly seven times brighter than the Neutron Star (NS)-NS merger event AT2017gfo. We show that this event can be explained by an… Expand
