Caballero-Garcia (ASU-CAS, \nCZ) on behalf of a larger collaboration, report:\n\nFollowing the detection of the short-duration GRB 190427A (Tohuvavohu et \nal. GCNC 24261), both the 30cm BOOTES-1 robotic telescope in Mazagon \n(Huelva, southern Spain) and the BOOTES-5/JGT robotic telescope at \nObservatorio Astronomico Nacional in San Pedro Martir (Mexico), \nautomatically responded at 04:35:01 UT (~46 s after trigger) and \n04:55:00 UT (~0.33 hr after trigger) respectively. No optical afterglow \nis detected down to 17 mag and 20 mag respectively. This is consistent \nwith the no-detection reported by Lipunov et al. (GCNC 24263) and Izzo \net al. (GCNC 24265). Further analysis is ongoing.",
