GRB 210919A: BOOTES-2/TELMA optical upper limit
Abstract
The 60cm BOOTES-2/TELMA robotic telescope at IHSM La Mayora (UMA-CSIC) in Algarrobo Costa (Malaga, Spain) automatically responded to the Swift trigger of short GRB 210919A (Tohuvavohu et al. GCNC 30846). Images were taken starting at 00:32 UT on 19 Sep (~4 min after trigger) under high airmass conditions. In the co-added 10 x 10 s exposure image (clear filter), no optical afterglow is detected within the reported XRT/Swift source position (Tohuvavohu et al. GCNC 30846) down to 17.5 mag. This non-detection is consistent with reports from Tohuvavohu et al.(GCNC 30846) and Lipunov et al.(GCNC 30847). We thank the staff at La Mayora for its excellent support.
