TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2121 SUBJECT: If the SN/GRB connection confirmed DATE: 03/04/09 05:33:01 GMT FROM: Vladimir Sokolov at SAO RAS V. Sokolov (SAO RAS) reports: Congratulations to all "GRB-fans"! At last! I will permit myself to make a short comment to GCN#2120 (T. Matheson et al.). If all "...classical GRBs originate from core-collapse supernovae", as was mentioned in the GCN #2120, it would inevitably have consequences for both a collimation angle, and the GRBs energy (see details in astro-ph/ 0102492 or astro-ph/0107399), and all the GRB scenarios.
