Troja (UTV, ASU), report on behalf of a\nlarger collaboration:\n\nWe carried out optical observations with the 8.1m Gemini-South Telescope\nin Cerro Pachon, Chile targeting the location of the short GRB 230217A\n(Moss et al. GCN 33339). We observed the position of X-ray Source 3\nreported by Capalbi et al. (GCN 33348) at 09:24:47 UT on 2023-02-20,\ncorresponding to ~2.5 d after the GRB trigger (Moss et al. GCN 33339,\nSvinkin et al. GCN 33349, Veres et al. GCN 33353). The target was\nobserved during twilight for 300 s in i-band.\n\nWithin the source localization, we do not find any obvious counterpart\nwhen compared to the PS1 catalog to depth i>22.8 AB mag (not corrected\nfor Galactic extinction along the line of sight). However, objects\nfainter than the PS1 limits are resolved in our observation and will\nrequire image subtraction to establish fading.\n\nFurther observations are planned.\n\nWe thank the staff of the Gemini Observatory for assistance in rapidly\nobtaining these observations.",
