GRB 210306A: NEXT optical observations
Abstract
We observed the field of GRB 210306A (D'Elia et al., GCN 29597) using the NEXT-0.6m optical telescope located at Nanshan, Xinjiang, China. Observations started at 16:11:33 UT on 2021-03-06, i.e., 12.29 hr after the BAT trigger. We obtained 15x200 s frames in the Sloan r-filter. The previously reported optical afterglow (e.g., D'Elia et al., GCN 29597; Watson et al., GCN 29598; Romanov F., GCN 29599; Strausbaugh et al., GCN 29600; Hentunen et al., GCN 29603; Stecklum et al., GCN 29604) is clearly detected in our stacked image, with r = 21.0 +/- 0.1 mag at 12.76 hr post-burst, calibrated with nearby PS1 stars.
