GRB 210205A: Nanshan/NEXT optical upper limit
Abstract
We observed the field of GRB 210205A (Dichiara et al., GCN 29397) using the NEXT-0.6m telescope located at Nanshan, Xinjiang, China. We obtained 3x40 s, 4x60 s, 12x90 s frames in the Sloan r-band, starting at 12:09:46 UT on 2021-02-05, i.e., 58.5 min after the BAT trigger. No optical source is detected in our stacked image at the enhanced XRT position (Osborne et al., GCN 29399), down to a limiting magnitude of r~19.9, calibrated with the nearby PanSTARRS field.
