Fynbo (DARK/NBI), and T. \nKruehler (MPE), report on behalf of a larger collaboration:\n\nWe observed the field of GRB 150302A (Lien et al., GCN 17526) with the \nNordic Optical Telescope (NOT) equipped with the ALFOSC imaging camera. \nObservations (4x300 s exposure) were carried out in the SDSS r filter, \nat a mean epoch 2016 Jun 23.94 UT (1.3 years after the GRB).\n\nAt the location of the optical afterglow candidate (Fynbo et al., GCN \n17527), we detect no source down to a limiting magnitude of r = 23.5, \ncalibrated against nearby SDSS stars. By comparing with our early epoch, \nwe conclude that the source has faded by more than 1 mag. Together with \nthe positional consistency with the enhanced XRT location (Goad et al., \nGCN 17534), we can thus now confirm it as the optical afterglow of GRB \n150302A.\n\nWe acknowledge excellent support from the NOT observing staff, in \nparticular John Telting.",
