a large collaboration report:

The 2-m Faulkes Telescope South automatically began observing GRB
130727A (Stroh et al. GCN Circ. 15046) on July 27 2013 at 17:01:22 UT
(~16 min after the burst trigger).

Within the XRT error circle (Perri et al. GCN Circ. 15048) we
find a fading uncatalogued object at coordinates

RA(2000.0)=   22:03:11.66
Dec(2000.0)= -65:32:18.7   (error 0.5")

with the following magnitudes
