D. Malesani (DARK/NBI and DTU Space), D. Xu (NAOC/CAS), A. de Ugarte 
Postigo (IAA-CSIC and DARK/NBI), R. Tronsgaard Rasmussen (NOT), P. Blay 
(NOT/IAC), report on behalf of a larger collaboration.

We observed the field of the Fermi GRB 160910A (Veres & Meegan, GCN 
19901; Racusin & Kocevski, GCN 19902) with the Nordic Optical Telescope 
(NOT) equipped with the AlFOSC imaging camera.

Observations started on 2016 Sep 11.847 UT, and consisted of 3x300 s in 
the SDSS r filter. We detect the afterglow reported by de Ugarte Postigo 
et al. (GCN 19907), and we provide coordinates (J2000):

RA = 14:45:46.04
Dec = +39:04:00.2

The expected uncertainty is <0.5". Comparing with nearby SDSS stars, we 
measure for the afterglow a magnitude r = 19.65 +- 0.01 (AB) at a mean 
time of Sep 11.8487 UT (27.04 hr after the GRB trigger).
