P. Kubanek, M. Jelinek, J. Gorosabel (IAA-CSIC), report on behalf of a larger collaboration:
"The 1.23m CAHA telescope responded automatically to GRB 120311A (trigger=517469, Markwardt et al. GCN 13032) starting optical observations on March 11.23381 UT (~3.05 minutes after the trigger). The optical afterglow (Melandri et al. GCNC 13033) is clearly detected in two I-band frames taken before dawn at I ~ 17.3."
