Castro-Tirado (IAA-CSIC), D. Hiriart and W. H. Lee (UNAM), S. Jeong and
I. H. Park (SKKU), I. Carrasco, A. Castellon, C. Perez del Pulgar (Univ.
de Malaga), S. B. Pandey (ARIES) and M. D. Caballero-Garcia (ASU-CAS,
CZ) on behalf of a larger collaboration, report:
Following the detection of the short-duration GRB 190427A (Tohuvavohu et
al. GCNC 24261), both the 30cm BOOTES-1 robotic telescope in Mazagon
(Huelva, southern Spain) and the BOOTES-5/JGT robotic telescope at
Observatorio Astronomico Nacional in San Pedro Martir (Mexico),
automatically responded at 04:35:01 UT (~46 s after trigger) and
04:55:00 UT (~0.33 hr after trigger) respectively. No optical afterglow
is detected down to 17 mag and 20 mag respectively. This is consistent
with the no-detection reported by Lipunov et al. (GCNC 24263) and Izzo
et al. (GCNC 24265). Further analysis is ongoing.
