D. Kopac (U. Ljubljana), C. Guidorzi (U. Ferrara), S. Kobayashi (LJMU), 
A. Gomboc (U. Nova Gorica), C.G. Mundell (U. Bath), on behalf of a large 
collaboration report:

The 2-m Liverpool Telescope began observing Swift GRB 160313A (D'Ai et 
al., GCN 19171) on March 13, 02:40:45 UT (3.5 minutes after the burst 
trigger). Inside the XRT error circle (Goad et al., GCN 19174) we find 
no source down to r'> 21.0 mag in a 6x10s exposure (at 36.5 min, mid 
time), as calibrated against nearby SDSS stars, in agreement with 
previous reports (Moskvitin et al. GCN 19172; Cucchiara et al. GCN 
19173; Klotz et al. GCN 19175).
