GRB 231216A: optical upper limits from the INAF Asiago Observatory
Abstract
We observed the field of GRB 231216A (Sbarrato et al., GCN Circ. 35378) from the INAF - Padova Astronomical Observatory located in Asiago (Italy) with the 1.8m Copernico telescope starting on 2023-12-16 at 20:24:48 UT (~ 1.8 hours after the burst). The observations have been carried out with the AFOSC camera in imaging mode using the r filter. No optical afterglow candidate is detected within the XRT error circle (Sbarufatti et al., GCN Circ .35391) down to a 3sigma limiting magnitude of r ~ 22.0 (AB; calibrated against the PanSTARRS catalogue).
