Discovered by L. Amaral, C. Jacques, C. Colesanti, E. Pimentel, I. Mussi, J. Ribeiro, M. Domingues, J. Amancio, P. Holvorcem, T. Napoleao on behalf of the Brazilian Transient Search - BraTS - at SONEAR Observatory, Oliveira, Brazil with three frames with 30 seconds exposure using an telephoto 200m f/1.8 + Canon 6D camera with magnitude 13.9 (magnitude correction= it's not 13.6 as stated in the discovery report) under limiting mag = 14.5. Nothing is visible at this location on the previous frame (limiting mag = 14.5) taken on 2019 Dec 25.1457 UT.
