Following the detection of GRB 220506A by MAXI/GSC (Urabe et al. GCNC 32001) and Swift (Evans et al. GCNC 32005), the BOOTES-5/JGT 0.6m robotic telescope at Observatorio Astronomico Nacional in San Pedro Martir (Mexico) observed the GRB location starting on May 7, 10:36 UT (~1.2 days after trigger) at high airmass. In the co-added image (15 x 60 s exposures in the clear filter), no optical afterglow is detected within the Swift/XRT error region (Osborne et al. GCNC 32006) down to 19.0 mag.
We thank the staff at Observatorio Astronomico Nacional in San Pedro Martir for their excellent support.
