Following the detection of GRB 210208A by INTEGRAL (Mereghetti et al. GCNC 29429), the 60 cm BOOTES-2/TELMA robotic telescope at IHSM La Mayora (UMA-CSIC) in Algarrobo Costa (Malaga, Spain) pointed to the position of the GRB, 17 deg away from the Galactic Center. No new source within the INTEGRAL/IBIS error box down to 17.3 mag is detected in the co-added image (2x60 s exposures, clear filter) obtained through a partially cloudy sky, at 06:17 UT on Feb 9 (~17.25 hr after trigger).

We thank the staff at La Mayora for their excellent support.
