Castro-Tirado (IAA-CSIC/UMA), report on behalf of a larger collaboration:\n\nWe observed the field of GRB 151022A (D'Avanzo et al., GCN Circ. 18436) with the 1.5m\nOSN telescope at Observatorio de Sierra Nevada (Spain). The observations\nwere carried out in the I band on Oct 22.79163 - 22.84025 (4.89 - 6.06 hours\npost bust). We do not detect any new optical source within the enhanced XRT \nerror circle (Beardmore et al., GCN Circ. 18444) down to a limiting magnitude of I ~21.5 mag.",
