TITLE: GCN CIRCULAR NUMBER: 24298 SUBJECT: LIGO/Virgo S190426c: COATLI Optical Observations of Galaxies DATE: 19/04/27 19:18:40 GMT FROM: Alan M Watson at UNAM Rosa L. Becerra (UNAM), Alan M. Watson (UNAM), Nat Butler (ASU), Eleonora Troja (GSFC/UMD), Simone Dichiara (UMD), Diego Gonz��lez (UNAM), Alexander Kutyrev (GSFC/UMD), William H. Lee (UNAM), Margarita Pereyra (UNAM), and Tanner Wolfram (ASU) report: We observed 98 galaxies selected from the NED/CLU list for LIGO/Virgo S190426c (Chatterjee et al, GCN Circ. 24237) with the COATLI 50-cm telescope and interim imager at the Observatorio Astron��mico Nacional on the Sierra de San Pedro M��rtir (http://coatli.astroscu.unam.mx) on the night of 2019-04-27 UTC. For each galaxy, we typically obtained 150 seconds of exposure in the w filter and obtained a typical 10-sigma limiting magnitude of 19.5. Our observations are listed below. Visual inspection reveals no obvious counterpart candidates. We thank the COATLI technical team and the staff of the Observatorio Astron��mico Nacional.
