TITLE: GCN CIRCULAR NUMBER: 18285 SUBJECT: GRB 150910A: VLA Detection DATE: 15/09/11 22:54:59 GMT FROM: Kate Alexander at Harvard K. Alexander (Harvard), T. Laskar (NRAO / UC Berkeley), and E. Berger (Harvard) report on behalf of a larger collaboration: We observed GRB 150910A (Pagani et al; GCN 18264) at multiple frequencies with the Karl G. Jansky Very Large Array (VLA) beginning 2015 September 11.10 UT (0.72 days after the burst). At a mean frequency of 9.8 GHz, we detect a radio source with a preliminary flux density of ~ 0.1 mJy at RA = 00:22:40.120 +/- 0.021 Dec = +33:28:21.750 +/- 0.036 consistent with the UVOT optical position (McCauley et al; GCN 18270) and the enhanced Swift/XRT position (Evans et al.; GCN 18271). Follow-up observations are planned.
