  "body": "Paul Vreeswijk, Annalisa De Cia (U. Iceland), Dong Xu (WIS), Daniele\nMalesani (DARK), Páll Jakobsson (U. Iceland) report on behalf of a\nlarger collaboration:\n\nUsing ALFOSC on the Nordic Optical Telescope (NOT) we have obtained R\n(3 x 300 s) and I-band (5 x 400 s) imaging of the field of the Swift\nGRB 111022B (Holland et al., GCN 12472), starting on 2011 October\n23.097 UT (roughly 9.3 hours after the burst). The seeing during the\nobservations was around 1\".\n\nWe do not detect any object within the enhanced XRT error circle\n(Beardmore et al., GCN 12478), down to limiting magnitudes of about\nR>23.2 and I>21.9 (calibrated against the USNO-B1 catalog).\n\nWe are grateful to the NOT observer, Terese Hansen (U. Copenhagen),\nfor obtaining these observations.",
