Discovered by L. Amaral, E. Pimentel, C. Jacques, C. Colesanti, C. Barreto, I. Mussi, J. Ribeiro, M. Domingues, J. Amancio, P. Holvorcem, T. Napoleao on behalf of the Brazilian Transient Search - BraTS - at Observatorio Campo dos Amarais, Bilac, Brazil in three frames with 60 seconds exposure using a 306mm f/2.9 reflector + CCD with magnitude 17.5 under limiting magnitude 19.5. Nothing is visible at this location on the previous frame (limiting mag = 19.5) taken on 2020 Mar. 27.2139 UT.
