TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4840 SUBJECT: GRB 060218 : GMRT observation [Correction and Improvement] DATE: 06/02/27 16:41:08 GMT FROM: Atish Kamble at Raman Research Inst Atish Kamble (Raman Research Institute [RRI], Bangalore, India), C. H. Ishwara Chandra (NCRA, Pune, India) and D. Bhattacharya (RRI) report on behalf of a larger GRB collaboration : The date of GMRT observation of GRB 060218 reported in GCN 4832 has a typo. The correct date of observation was 21 Feb 2006 and not 20 Feb 2006. Our apologies for the inconvenience it might have caused. With further analysis of the data (same observation) we could improve the upper limits on the radio afterglow flux of GRB 060218. We now put a 3 sigma upper limit of ~ 0.3 mJy.
