Description
I will present a summary of the observational properties of kilonovae. This sample includes AT2017gfo (associated with GW170817) and the more extensive but more sparsely sampled set of kilonovae identified in short and, more recently, in long-duration gamma-ray bursts. The broad photometric properties (peak magnitudes, timescales) are similar in many cases in which kilonovae are seen. However, there are also events in which they are apparently much fainter. I will also highlight the recent mid-IR observations of a kilonova in the long-duration GRB 230307A, providing the first late time and first mid-IR spectroscopy of a kilonova and an important observational focus for future modelling.
