A. Volnova (IKI), R.Inasaridze (AAO), O. Kvaratskhelia (AAO), V. 
Ayvazian(AAO), I. Molotov (KIAM), A. Pozanenko (IKI)  report on behalf 
of  larger GRB follow-up collaboration:

We observed the field of the Swift GRB 130829A (Grupe et al., GCN 15131) 
with AS-32 (0.7m) telescope of Abastumani Observatory  on Aug. 29 
starting (UT) 18:56. We obtained several unfiltered images of 120 s 
exposure. Our images cover 100% of the BAT error circle. In the BAT 
error localization  GRB 130829A (Grupe et al., GCN 15131) we do not 
identify any new source in comparison with SDSS.  A photometry of 
combined image against nearby SDSS stars (R magnitude, transformed by 
Lupton gri -> R transformation) is following
