Following the detection of GRB 240205B by Fermi (GCNC 35682) and Swift (Palmer et al., GCNC 35683), the 0.6m BOOTES-7 robotic telescope at San Pedro de Atacama (Chile) pointed to the burst position starting on Feb 6 at 00:15 UT (i.e. ~2 h after trigger). Images are being gathered, through passing clouds, in different optical bands (griz). In any case, the optical afterglow reported by MASTER (Lipunov et al. GCNC 35684), is well detected in all images, for which we measure a g-band mag of 15.5 +/- 0.1 (on a 60s image taken at 00:33 UT). Spectroscopic observations are encouraged.
We thank the staff at San Pedro de Atacama Celestial Explorations observatory for their excellent support.
