Discovered by C. Jacques, C. Colesanti, C. Barreto, E. Pimentel,J. Ribeiro, M. Domingues, J. Amancio, L. Amaral, P. Holvorcem, T. Napoleao on behalf of the Brazilian Transient Search - BraTS - at SONEAR 2 Observatory, Belo Horizonte, Brazil in three frames with 10 seconds exposure using an astrograph 280mm f/2.2 + CCD unfiltered, with magnitude 14.9 under limiting mag = 16.5. Nothing is visible at this location on the previous frames (limiting mag = 16.5) taken on 2023 Jun 10.0858 UT.
