Hermelo (IRAM Granada), on behalf of\na larger collaboration, report:\n\nFollowing the detection of GRB 141109B by Swift (Melandri et al. GCNC\n17038), observations with the IRAM 30m antenna (+NIKA) at Pico Veleta\n(Spain) were triggered on 9 Nov under good conditions but at relatively\nlow elevation (25 deg). At the position of the X-ray afterglow (Beardmore\net al. GCNC 17045), we detect no mm afterglow (at 150 GHz) down to a\npreliminary flux density of 1 mJy (3 sigma) on Nov 9, 20:30 UT (mid time).\nWe acknowledge excellent assistance from the IRAM observers.",
