Kuutma (NOT and Tartu \nObs.), report on behalf of a larger collaboration:\n\nWe observed again the optical counterpart of GRB 160410A (Gibson et al., \nGCN 19271) with the Nordic Optical Telescope (NOT) equipped with ALFOSC. \nObservations started on April 11.87 UT and consisted of 4x900 s \nexposures in the SDSS r band.\n\nAt a mid time of 40.37 hr after the GRB, we do not detect any longer the \noptical afterglow down to a 3-sigma limiting magnitude of r > 25 (AB), \ncalibrated against nearby SDSS stars. The corresponding decay index (F \npropto t^-alpha) between our two NOT observations (Malesani & \nKirkpatrick, GCN 19925) is constrained to be alpha > 0.9. The object \nclosest to the GRB position (with r ~ 24) lies 4.7\" away, so we cannot \nsingle out any obvious host galaxy candidate to the GRB, down to the \nquoted limiting magnitude.",
