We observed the field of GRB 240713A detected by SVOM/ECLAIR and Fermi/GBM (Schanne et al., GCN Circ. 36854;
Burns et al., GCN Circ. 36856) from the INAF - Padova Astronomical Observatory located in Asiago (Italy) with the Schmidt
telescope starting on 2023-07-14 at 00:06:36 UT (~ 22.07 hours after the burst) with the r filter.
No optical afterglow candidate is detected within the entire 1 deg x 1deg field of view of the telescope, which covers the whole
error circle of SVOM/ECLAIR and the positions of the EP-FXT sources (Yang et al., GCN Circ. 36859), down to a 3sigma limiting
magnitude of r ~ 20.7 (AB; calibrated against the PanSTARRS catalogue).
