A. Sota, J. Gorosabel and A. J. Castro-Tirado (IAA-CSIC Granada) on behalf
of a larger collaboration, report:

"Following the detection of GRB 131127A by Swift (Markwardt et al. GCNC
15516), we have conducted I-band observations with the 1.5m OSN telescope at
Observatorio de Sierra Nevada (Granada, Spain), starting on 27 Nov 18:26
UT,(i.e. 8.2-hr post burst). A stack of 17 x 300s images shows nothing at
the enhanced Swift/XRT position (Evans et al. GCNC 15520) down to I = 21".
