TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2881 SUBJECT: GRB 041219: Radio Afterglow Detection DATE: 04/12/20 05:50:16 GMT FROM: Alicia Soderberg at Caltech A. M. Soderberg (Caltech) and D. A. Frail (NRAO) report on behalf of the Caltech/NRAO/Carnegie GRB Collaboration: "We observed the field of GRB 041219 (GCN #2866) with the Very Large Array on 2004 Dec 20.14 UT (t ~ 1.1 days after the burst). At 8.5 GHz we detect a radio source coincident with the optical afterglow reported by Blake & Bloom (GCN #2870) with a flux density of 0.45 +- 0.05 mJy. Further observations are planned." ----------------------------------------------------------------- Alicia M.
