We observed GRB 131030A (Swift Trigger 576238; Troja et al. GCN 15402)
using the RoboPol (http://robopol.org) polarimeter on the 1.3m Skinakas
observatory  telescope (Greece). We confirm the presence of an uncatalogued
source  at the location (RA=23h00m16s, Dec=-05d22m05s). Preliminary analysis
showed that emission of the source is linearly polarized at high significance.

Further analysis will be presented elsewhere.
