larger GRB follow-up collaboration:
We observed the field of GRB 150302A (Lien et al., GCN 17526) with
AZT-33IK telescope of Sayan observatory (Mondy). We obtained several
images in R-filter on Mar., 02, starting (UT) 15:55:19. Within enhanced
XRT error circle (Goad et al., GCN 17534) we do not detect any optical
source. In particular, we do not detect the afterglow candidate (Fynbo
et al., GCN 17527). Upper limit is following
