GRB 200829A: Nanshan/NEXT optical observations
Abstract
We observed the field of GRB 200829A (Siegel et al., GCN 28307) using the NEXT-0.6m telescope located at Nanshan, Xinjiang, China. We obtained a series of frames in the Sloan g-/r-/i- bands, starting at 19:55:23 UT on 2020-08-29, i.e., 5.93 hr after the BAT trigger. The GRB optical afterglow (e.g., Pozanenko et al., GCN 28308; Kuin et al., GCN 28311; Ursi et al., GCN 28314; Lipunov et al., GCN 28315; Vinko et al., GCN 28316; Hentunen & Nissinen, GCN 28318; Moskvitin et al., GCN 28322) is clearly detected in our images. Preliminary photometric measurements are as follows: Filter T-mid(hr) Mag Mag_err SDSS-g 6.72 18.89 0.04 SDSS-r 5.98 18.77 0.04 SDSS-i 6.40 18.50 0.05 calibrated with nearby Pan-STARRS stars.
