          Abstract

          With the advent of the follow-up of large sky localization regions from gravitational-wave detectors and gamma-ray burst telescopes with wide field-of-view telescopes, the need for efficient follow-up of the many identified candidates is required. Due to limited telescope time, it is important to create prioritized lists of the many candidates identified. Towards this end, we use \text{\astrorapid}, a multi-band photometric lightcurve classifier, to differentiate between kilonovae, supernovae and other possible transients. We demonstrate our method on both ideally sampled, simulated lightcurves, as well as the photometric observations of real events. We show that after only a few days of observations of an astronomical object, it is possible to rule out candidates as supernovae and other known transients
