TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3501 SUBJECT: Update on Swift-BAT GRB 050528 (Trigger 130679) DATE: 05/05/28 15:57:03 GMT FROM: Scott Barthelmy at NASA/GSFC S. Barthelmy (GSFC), S.T. Holland (GSFC/USRA), N. Gehrels (GSFC), M. Goad (Leicester U.), C. Gronwall (PSU), H. Krimm (GSFC/USRA), C. Markwardt (GSFC/UMD), D. Palmer (LANL), P. Roming (PSU) on behalf of the Swift team The putative Swift-BAT burst GRB050528 (Trigger 130679 at 04:06:45 UT) (GCN 3496) is still uncertain. Intermittant problems with the transfer of data from Malindi to the US have prevented a final determination of the validity of this BAT trigger. The file transfer problem is being worked, and when we get the data from the trigger time interval, we will issue an update. We apologize for the delay and any inconvenience in follow-up observing programs.
