on behalf of a larger collaboration report:

The 2-m Faulkes Telescope North automatically began observing INTEGRAL
GRB 140320B on March 20 at 09:31:27 UT (~4.6 min after the burst trigger).

We find a fading uncatalogued object at coordinates

RA(2000.0)=   09:42:14.17
Dec(2000.0)=  +60:16:05.7  (error 1.0")

with i=19.7 +- 0.1 mag at 16 minutes after the GRB,
calibrated against nearby SDSS-I stars.
