follow-up collaboration:
We observed the field of GRB 160804A (Marshall et al., GCN 19761) with
SANTEL-650 (0.65m) telescope of UAFO/ISON-Ussuriysk observatory. We
obtained several unfiltered images starting on August 04 (UT)
12:03:56. We clearly detected optical source reported by Breeveld et
al. (GCN 19764), Tyurina et al. (GCN 19768), Malesani et al. (GCN
19770), Moskvitin et al. (GCN 19771), Xu et al. (GCN #19773) and Bolmer
et al. (GCN 19774). Preliminary photometry of a combined image is following
