M. Jelinek, A.J.Castro-Tirado, J. Gorosabel (IAA CSIC Granada), Petr Kubanek (GACE Valencia), S. Vitek (FEL CVUT Praha), A. de Ugarte Postigo (ESO Santiago), on behalf of a larger Collaboration: report: "We observed the optical afterglow of GRB 080605 (Kann et al. GCN 7829, Sbarufatti et al. GCN 7828, Gomboc et al. GCN 7831) with the 30cm BOOTES-1B and with the 60cm BOOTES-2/TELMA robotic telescopes in southern Spain. The sequence of observations started 43s after the GRB trigger. We clearly detect a 15th mag transient outshining the nearby star in R-band (BOOTES-2/TELMA) and without filter (BOOTES-1B). "
