P. D'Avanzo, S. Covino, A. Melandri (INAF/OAB) L. Di Fabrizio (INAF/TNG) report on behalf of the CIBO collaboration:

We observed the field of GRB 140206A (Lien et al., GCN 15784; Gotz et al. GCN 15785) using the DOLORES camera on the 3.6-m TNG Telescope at Canary Islands.

The optical afterglow (Oates & Lien GCN 15787; Yurkov et al. GCN 15788; Xu et al. GCN 15789; Volnova et al. GCN 15792; Oates & Lien GCN 15795; Sonbas et al. GCN 15797) is clearly detected with R = 18.7 +/- 0.1 (calibrated against the USNOB1 catalogue) at t-t0 = 12.52 hours.

Further observations are ongoing.
