Mason (Gemini) report on behalf of a larger collaboration:\n\nWe obtained observations of the field of GRB 120320A (Markwardt et al.\nGCN13071) with both Gemini-N/GMOS in i and z, and UKIRT/WFCAM in J, H\nand K. Our first observations began approximately 30 minutes after the burst,\nand continued for a further 2 hours.\n\nWithin the refined X-ray error circle (Beardmore et al. GCN 13075) we detect a\nvery faint source in our GMOS imaging at position (accuracy ~0.5\"):\n\nRA(2000)=14:10:04.28\ndec(2000)=08:41:47.9\n\nThe source has i~25.7+/-0.3 and z~25.3+/-0.3. It is undetected in the UKIRT\nimaging to preliminary limits of J>21.6, H>20.0 and K>19.5.\n\nThis source could therefore be related to either the afterglow or the host galaxy of\nGRB 120320A, but at the current time we cannot make any statements about fading.",
