We do not see any optical source within the revised SWIFT/XRT position (Beardmore et al. GCNC 4895) down to R = 21. In particular, we do not see any counterpart at this time to the MASTER source reported by Lipunov et al. (GCNC 4892) in agreement with D'Avanzo et al. (GCNC 4893). This message can be quoted.
