report:

The 2-m LCOGT Faulkes Telescope North began observing Fermi-LAT GRB 
160816A (Racusin et al., GCN 19802) on August 17, 07:23:08 UT (13.9 
hours after the burst trigger). Inside the Swift-XRT error circle of the 
X-ray afterglow candidate (Kennea et al., GCN 19806) we find an 
uncatalogued source at the following position:

RA(J2000)=  21:29:38.58
Dec(J2000)= +37:07:58.7

with an uncertainty of 1.0 arcsec and r~21.0 +- 0.2 mag (AB).
