report:

The 1-m LCOGT McDonald telescope began observing Swift GRB161017A (Troja 
et al., GCN 20064) in the SDSS r filter on October 18, 10:03 UT (~0.67 
days since the GRB). We detect the optical afterglow (Yurkov et al. GCN 
20063; Troja et al. GCN 20064; de Ugarte-Postigo et al. GCN 20069; 
Fujiwara et al GCN 20070; Melandri et al. GCN 20071) with r=18.95 +- 
0.10 mag at 0.68 days mid epoch, as calibrated against nearby SDSS stars.
