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:
RA=08:57:37.30
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.
