F.J. Virgili, C.G. Mundell (LJMU), J. Japelj, A. Gomboc (U.
Ljubljana), R.J. Smith (LJMU), A. Melandri (INAF-OAB) report:

The 2-m Liverpool Telescope robotically followed up GRB 131030A (Swift
Trigger 576238; Troja et al. GCN 15402) immediately after the GRB
trigger time.  The automated procedure detected an uncatalogued source
at the location of the UVOT source. We confirm the fading nature of the
object with

R = 16.9 ± 0.2 mag (vs. USNOB1) 34.8 min after the burst.

thereby confirming this as the GRB afterglow.

Observations and analysis are ongoing.
