Liimets (NOT & Tartu Obs.) report on behalf of a larger collaboration:\n\nWe observed the field of GRB 090530 (Cannizzo et al., GCN 9438) with the \nNOT equipped with the MOSCA camera. Observations were carried out in the \nR band, starting on 2009 May 30.879 UT (17.8 hr after the GRB).\n\nThe optical afterglow (Cannizzo et al., GCN 9438; Flewelling et al., GCN \n9439; Morgan et al., GCN 9440) is clearly detected in a single 300s \nexposure, with a magnitude R = 21.6 assuming R = 18.17 for the USNO star \nat RA = 11:57:41.68, Dec = +26:35:43.3.",
