We observed the field of GRB 210704A (Berretta et al., GCN Circ. 30375; D'Ai et
al., GCN Circ. 30379; Malacaria & Meegan, GCN Circ. 30380; Kim et al., GCN Circ.
30384) with the OSIRIS instrument on the 10.4 meter GTC telescope.
We observed at two epochs. The first epoch was at 2.10 days after burst and the
second at 5.10 days after burst. At both epochs, we detect a source at the
position of the candidate optical afterglow (Kim et al., GCN Circ. 30384
