Starting on the night 24/03/2015 02:48 UT we observed the field GRB 150323B
(J. R. Cummings GCN 17619 ). We imaged the X-ray positions published by P.
D'Avanzo et al. GCN 17634.
 On the coadded R band images (total exposure = 1500 sec) we found marginal
optical sources on the positions coincide with soure 1 and source 2.
