Cardenes and Anlaug Amanda\nDjupvik (NOT) report:\n\nWe observed the field of GRB 080613B (Markwardt et al., GCN 7873) on\nJune 13 with the NOT on La Palma using StanCam\nand NOTCAM. Observations of 4x300s in R band were obtained with\nStanCam starting at UT 21:57 and 5x270s with NOTCAM in the Ks band\nstarting UT 23:17.\nIn the stacked images of both filters we do not detect any optical\ncounterpart within the XRT error circle (Mao et al. GCN 7875). The\nlimiting magnitudes are about R=22 mag and Ks=17.6 based on USNO and\n2MASS stars in the field respectively.\n\n[GCN OPS NOTE(14jun08): Per author's request, the two references\nwere added and the author list order was chanegd.]",
