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
