Hiriart, W. H. Lee (UNAM), \nI. H. Park (SKKU) and M. D. Caballero-Garcia (ASU-CAS, CZ) on behalf of \na larger collaboration, report:\n\nFollowing the detection of GRB 191016A by Swift (Gropp et al., GCNC \n26008), the BOOTES Network robotic telescopes automatically responded to \nthis burst at the different astronomical stations worlwide.\n\nThe 60cm BOOTES-5/JGT robotic telescope at Observatorio Astronomico \nNacional in San Pedro Martir (Mexico) gathered images (clear-filter) \nstarting at 04:15:06U T (6.0 min after the GRB onset).\n\nThe 60cm BOOTES-2/TELMA robotic telescope at IHSM La Mayora (UMA-CSIC) \nin Algarrobo Costa (Spain) obtained images (i-band filter) starting at \n04:15:15 UT (6.3 min after the GRB onset).\n\nThe 30cm BOOTES-1B robotic telescope at INTA-CEDEA in Mazagon (Huelva), \nsouthern Spain, imaged the field (clear filter) starting at 04:16:32 UT \n(7.5 min after the GRB onset).\n\nThe optical afterglow (Watson et al. GCNC 26010, Zheng et al. GCNC \n26011, Watson et al. GCNC 26015) is detected in all three BOOTES \nstations. Detailed data analysis is ongoing.\n\nFollow-up observations were also triggered at the 1.5m OSN telescope in \nObservatorio de Sierra Nevada, Granada (Spain) starting at 19:56 UT \n(15.8 h after the GRB trigger). The afterglow was still detected in the \nR-band, for which we measure R = 19.8 +/- 0.1 (preliminary).\n\nWe thank the staff at Observatorio Astronomico Nacional in San Pedro \nMartir, IHSM La Mayora, INTA-CEDEA and Observatorio de Sierra Nevada for \nthe excellent support.",
