C.G. Mundell (LJMU) report:

The 2-m Liverpool Telescope robotically followed up GRB130408A (Swift  
trigger 553132, Lien et al., GCN 14361) 19.42 min after the GRB  
trigger time observing with SLOAN-gri filters.

The automatic LT-TRAP procedure detected an uncatalogued fading source  
candidate at:

Dec=-32:21:38.90    (J2000)

with magnitude R~16.5 mag (vs USNOB1) ~20 min after the burst trigger.  
The object is clearly fading in all filters and we suggest this is the  
optical afterglow of GRB130408A.

Observations and analysis are ongoing.
