TITLE: GCN CIRCULAR NUMBER: 17545 SUBJECT: GRB 150301C: VLA Observations DATE: 15/03/04 23:18:10 GMT FROM: Tanmoy Laskar at Harvard U T. Laskar, E. Berger (Harvard) and D. Fox (PSU) report on behalf of a larger collaboration: "We observed GRB 150301C (Lien et al; GCN 17512) with the VLA beginning on 2015 March 04.03 UT (2.77 days after the burst) at a mean frequency of 9.8 GHz. No radio counterpart is detected in the 90-minute observation within the XRT error circle (Evans et al; GCN 17536) to a 3 sigma upper limit of 18 uJy. The 90-minute observation covers the full BAT error circle and does not contain any radio source brighter than the NVSS flux limit. Well-detected sources fainter than the NVSS limit have been identified for possible future monitoring. We thank the VLA staff for scheduling and obtaining these observations."
