report:

We observed the afterglow of Fermi GRB 130702A (Singer et al., GCN
14967, Cheung et al., GCN 14971; Collazzi et al., GCN 14972), and
their progenitor Supernova SN 2013dx (Schulze et al. GCN 1994; Cenko
et al. GCN 14998) with Russian-Turkish 1.5-m telescope (RTT150,
Bakirlitepe, TUBITAK National Observatory, Turkey) on Aug., 28 starting
at UT 18:21:58. We obtained several images with exposure of 300
seconds in R band. A preliminary photometry of the GRB afterglow + SN
2013dx + host galaxy, based on two SDSS stars suggested by Schulze et
al. (GCN 14978):
