collaboration report:
The 2-m Faulkes Telescope North automatically began observing
GRB 120724A (D'Avanzo et al. GCN Circ. 13510) on July 24 2012,
06:42:31 UT corresponding to 209 seconds post burst trigger
with BVRi' filters. Within the XRT error circle we found the
following uncatalogued fading source,
R.A. = 16:20:43.21
Dec = +03:30:29.3 (J2000)
with an uncertainty of about 1" with a magnitude of
20.5 +/- 0.3 in the i band at 13.8 minutes, calibrated
against nearby USNOB-1 stars. The source is also visible
in stacked R-band frames.
