report on behalf of larger GRB follow-up collaboration:
We observed GRB 160623A (Vianello et al., GCN 19553; Mailyan et al.,
GCN 19555; Frederiks et al., GCN 19554) with Zeiss-1000 (East) 1-m
telescopes of Tien Shan Astronomical Observatory. We obtained several
images in R filter starting on June 24 (UT) 19:19:17. We detect optical
transient associated with GRB 160623A (Pozanenko et al., GCN 19561;
Butler et al., GCN 19567). Preliminary photometry of combined image
is following
