J.P.U. Fynbo (DARK/NBI), A. de Ugarte Postigo (IAA-CSIC, DARK/NBI),
T. Kruehler (ESO) report on behalf of a larger collaboration:

We observed the field of GRB 150302A (Lien et al., GCN 17526) using the 
2.5m Nordic Optical Telescope with AlFOSC. Observations starting at 
05:59 UT (17 min after the GRB) reveal an optical counterpart within the 
XRT error box at coordinates 11:42:07.43 +36:48:38.9 (J2000.0), with a 
magnitude of r=22.3, calibrated against SDSS field stars.
