Burns (GSFC) report on behalf of the Fermi-GBM Team:\n\nAt 09:07:37 UT on 14 May 2020, the Fermi Gamma-ray Burst Monitor (GBM) \ntriggered and located GRB 200514B (GCN 27736, Fermi-GBM Team). \n\nFollow-up observations by the Zwicky Transient Facility identified ZTF20aazpphd \nas a potential optical counterpart to GRB 200514B (Ahumada et al., GCN 27737).\nZTF20aazpphd was subsequently observed by ATLAS, \nwho found no evidence for rapid decline (Smartt et al., GCN 27738),\ncontrary to what expected for a short GRB afterglow.\n\nWe also verified that, when GBM triggered on GRB 200514B, the source position for \nZTF20aazpphd as observed by GBM was occulted by Earth and therefore unobservable. \nWe therefore conclude that the optical transient ZTF20aazpphd is unrelated to GRB 200514B.",
