TITLE: GCN CIRCULAR NUMBER: 11549 SUBJECT: GRB 101219b. Possible radio afterglow detection. DATE: 11/01/10 08:26:41 GMT FROM: Dale A. Frail at NRAO Dale A. Frail (NRAO) reports on behalf of a larger collaboration: "We responded to a request (GCN#11516) for further observations of the long-lived optical afterglow of GRB 101219B. The Expanded Very Large Array (EVLA) observed a field toward this GRB (GCN#s 11473, 11482) on 2011 January 7.03 UT at a center frequency of 8.46 GHz. In a preliminary reduction of the data, we detect a weak radio source (Flux=71+/-15 uJy) at RA(J2000)=00:48:55.40 (+/-0.01) and Dec(J2000)=-34:34:00.1 (+/-0.7) that may be the afterglow of GRB 101219B. No further observations are planned.
