Turku) report on behalf of \na larger collaboration:\n\nWe observed the field of GRB 150323C (Amaral-Rogers et al., GCN 17621; \nStanbro, GCN 17627) using the Nordic Optical Telescope (NOT) located in \nLa Palma. The mean time of the observation was March 28.21 UT, that is \n4.49 days after the GRB. A 20 min exposure was collected using the SDSS \nr filter.\n\nClose to the position of the optical afterglow (Xu et al., GCN 17625; \nWatson et al., GCN 17632), we detect an object with r = 23.6 +- 0.2 AB \n(calibrated against nearby SDSS stars). This source is also marginally \ndetected in the archival SDSS images with a comparable (though \nuncertain) brightness, and therefore an underlying galaxy must be \ncontributing a significant fraction of the light.\n\nWe note a small, but significant offset between the afterglow and the \ngalaxy positions. By registering astrometrically the afterglow image by \nXu et al. (GCN 17625) with the new NOT data, we find an offset of \napproximately 0.65\". Such an offset is not unprecedented, so that the \nSDSS/NOT object is still a viable host galaxy candidate for GRB 150323C.\n\n[GCN OPS NOTE(30mar15):  Per author's request, JH's affiliation was changed.]",
