collaboration:
We continued observation of the Swift GRB 140419A (Marshall et al., GCN
16118) with AZT-33IK telescope of Sayan observatory (Mondy) on Apr.
19-21. We took several images in R-filter. On a stacked image we clearly
detected the optical afterglow (Zheng et al., GCN 16119; Guver et al.,
GCN 16120; Butler et al., GCN 16121; Kuin et al., GCN 16123; Hentunen
et al., GCN 16126). Details of a photometry are the following:
