(GCN 26741), we report a previous SAGUARO\n(Lundquist et al. 2019) detection at the position of the candidate\nZTF20aafeaqk (AT2020vx), from 2019 Nov 24.  The object was detected in a\nstack of 4 images at the location of the transient (RA = 7:08:43.698, Dec\n=14:38:15.336).\n\nMJD | AB Magnitude | Error\n\n58811.4420504 | 20.86 | 0.17\n\nThis detection was in data taken with the 1.5m Catalina Sky Survey (CSS)\ntelescope on Mt. Lemmon, AZ during routine operations, calibrated to Gaia G.\n\nWe believe ZTF20aafeaqk (AT2020vx) to be unrelated to the LIGO/Virgo event\nS200114f.\n\nSAGUARO is supported by the National Science Foundation under Award Nos.\nAST-1909358 and AST-1908972.",
