Using the 0.92m Asiago Schmidt telescope, we observed the field of GRB 190613B 11.954 h after the burst (D���Ai et al. GCN 24807) in g, r and i.
We detected a source consistent with the optical and X-ray afterglow (Burgess et al. GCN 24808, Beardmore et al. GCN 24812, Bissaldi et al. GCN 24814, Marshall et al. GCN 24817, Zheng & Filippenko GCN 24818, Ukwatta et al. GCN 24820, Page et al. GCN 24823) in g band images while we could only set upper limits in the other bands.
The measured magnitude and 2.5-sigma upper limits are listed below:
