Castro-Tirado (IAA-CSIC, Granada) on behalf of a larger\ncollaboration report:\n\n\"We have observed the field of GRB 081003A detected by INTEGRAL\n(Mereghetti et al. GCN 8314) with the 1.5m OSN telescope at Sierra Nevada\nObservatory (Granada, Spain). The observations consisted of 6x300s in\nI-band, 2x300s in R-band and 2x300s in V-band (5.07, 6.17 and 5.31h after\nthe burst trigger respectively). We do not detect any new optical source\nwithin the Swift/XRT error box (Page et al. GCN 8319) down to 3-sigma\nlimiting magnitudes of I > 22.0 and R > 22.5. We note, however that there\ncould be a marginal object (with low S/N significance in the I-band frame)\nat coordinates (J2000): R.A.: 17:29:33.85, Dec.: +16:34:14.1 (+/-0.7\"),\nconsistent with the XRT error box. Deeper observations would be needed in\norder to confirm the reality of this source.\"",
