GRB 230414B: Dabancheng/GHOST optical observations
Abstract
We observed the field of GRB 230414B detected by Swift (A. D'Ai et al., GCN 33612) with the GHOST-0.5m telescope located at Dabancheng, Xinjiang, China. Observations started at 18:27:56 UT on 2023-04-14, i.e., 2.23 hr after the Swift/BAT trigger, and 20x120 s images were obtained all in the Sloan r filter. The afterglow reported before (Pankov et al., GCN 33615; Lu et al., GCN 33616; Raman et al., GCN 33618; Ghosh et al., GCN 33620; Moskvitin et al., GCN 33622; Malesani et al., GCN 33623) is clearly detected in the stacked image with a brightness of r = 20.1 +/- 0.1 mag, calibrated with nearby stars from the Pan-STARRS catalog.
