Iceland) report on behalf of a large collaboration:\n\nWe observed the field of GRB 110422A (Mangano  et al., GCN 11957) at\nthe Nordic Optical Telescope (NOT) equipped with ALFOSC. We obtained\n2x300 s R-band images with a median time 21:11:33.3 UT (i.e., 5.49397\nhr after the BAT trigger). The images, with an airmass ~1.5,  were\ntaken under the windy condition.\n\nA new optical source is detected at coordinates\n\n(RA,Dec)(J2000.0) = (07:28:11.06, +75:06:25.00)\n(error-radius:  ~ 0.1 arcsec),\n\nbeing consistent with the finding in Elunko et al. (GCN 11958) and\nGres et al. (GCN 11960). Note that this position is southwest of and\noutside the XRT error circle reported at http://www.swift.ac.uk/sper/.\nThe source has R~20.0 mag, calibrated with the #1651-0050630 star\n(R1=19.08) in the USNO B1 catalog.\n\nFurther observation is planned as long as the weather could stay\nobservable at La Palma.",
