J. Kelemen (kelemen at konkoly.hu) on behalf of the GRB OT observing program
at the Konkoly Observatory.

Starting on the night 23/03/2015 we observed the field GRB 150323C
(A. Amaral-Rogers et al. GCN 17621 ). On the position reported by D. Xu et al.
(GCN 17625) according our coadded R images we confirmed the presence of a 
marginal optical source in R band.
