GRB 220708A: BOOTES-5/JGT early optical upper limit
Abstract
Following the detection of GRB 220708A by Swift (D'Elia et al. GCNC 32343), the BOOTES-5/JGT 0.6m robotic telescope at Observatorio Astronomico Nacional in San Pedro Martir (Mexico) observed the GRB location starting on Jul 08, 04:40:14 UT (~ 45 s after trigger). In the early co-added image (30 x 10 s exposures in the clear filter), no optical afterglow is detected within the enhanced Swift/XRT error region (Osborne et al. GCNC 32347) down to 20.5 mag. We thank the staff at Observatorio Astronomico Nacional in San Pedro Martir for their excellent support.
