(KIAM) report on behalf of larger GRB follow-up collaboration:

We continue observations of the afterglow  (Singer et al., GCN 14967) of 
GRB 130702A  (Cheung  et al., GCN 14971; Collazzi  et al., GCN  14972) 
with AZT-22 telescope of Maidanak observatory.  A preliminary photometry 
of combined images is based on two SDSS stars suggested by Schulze et 
al. (GCN 14978) and used in our previous observations (Pozanenko et al, 
GCNs 14988, 14996)
