"The 2-m Liverpool Telescope robotically followed up GRB 120311A  
(SWIFT trigger 517469, Markwardt et al., GCN 13032) 14.4 min after the  
GRB trigger time. The automatic "detection mode" procedure detected an  
uncatalogued afterglow candidate close to the XRT error circle (7  
arcsec from its centroid) at:

18:12:22.166   +14:17:46.3   (J2000)

with magnitude R = 19.1 mag (vs USNOB1) 16 min after the burst.

Observations and analysis are ongoing.
