TITLE: GCN CIRCULAR NUMBER: 21041 SUBJECT: Swift trigger 750096 - OT candidate DATE: 17/04/27 03:39:16 GMT FROM: Nial Tanvir at U.Leicester N. R. Tanvir (U. Leicester) reports: I note that the MASTER optical transient reported by Lipunov et al. (GCN 21040) coincides with an AGN for which SDSS gives a magnitude of r=16.1 (consistent with the MASTER source) and a redshift of z=0.101. This suggests there is no compelling reason for it to be associated with Swift trigger 750096.
