Following the detection of short GRB 230228A by Swift (Dichiara et al. GCN 33378), we triggered the 10.4 m Gran Telescopio de Canarias (GTC) in La Palma (Spain) to image the GRB location with the OSIRIS instrument in two epochs (Mar 1 20:16 UT and Mar 3, 20:02 UT, 1.6 and 2.6 days post-burst respectively). Within the XRT error region, a constant brightness (z-band magnitude = 23.6) is found, which we suggest as the potential host galaxy of this burst.
We thank the excellent support from the GTC staff.
