TITLE: GCN CIRCULAR NUMBER: 18014 SUBJECT: GRB 150711A: Observations from the 2.5m NOT DATE: 15/07/11 23:51:28 GMT FROM: Antonio de Ugarte Postigo at IAA-CSIC Antonio de Ugarte Postigo (DARK/NBI), and Vincent Van Eylen (Aarhus University) report on behalf of a larger collaboration: We observed the field of GRB 150711A (Bernardini et al. GCN 18011) with the 2.5m Nordic Optical Telescope (NOT) equipped with AlFOSC starting at 21:18 UT (2.80 hrs after the trigger). The observation consisted of 3x300s in r-band and 3x300s in i-band and was performed at high airmass and with a seeing of ~ 3". We do not detect any source within the XRT error box (Osborne et al. GCN 18012) down to a limiting magnitude of r ~ 21.5. [GCN OPS NOTE(12jul15): Per author's request, a typo in the spelling of VVN's name was corrected.]
