TITLE: GCN CIRCULAR NUMBER: 6619 SUBJECT: Swift detection of a possible burst (Trigger 284850) DATE: 07/07/14 04:20:07 GMT FROM: Scott Barthelmy at NASA/GSFC D. Grupe (PSU), S. D. Barthelmy (GSFC), D. N. Burrows (PSU), M. M. Chester (PSU) and N. Gehrels (NASA/GSFC) report on behalf of the Swift Team: At approximately 03:18 +/-5min UT BAT triggered on a possible GRB (trigger 284850). Swift automatically slewed to the location RA=43.94 Dec=+30.24 (J2000). The uncertainty is 6 arcmin. We are uncertain about both the time and the location at this time because the trigger occurred during a TDRSS outage, so most of the regular TDRSS Notices were lost. We are also in the middle of the computer downtime as announced earlier today, so analysis of the full Malindi downlink data will have to wait until late Saturday UT. We wish to thank J. Knavel of the Swift Operations Team for notifying the science team that Swift had slewed to a GRB. Burst Advocate for this burst is D. Grupe (grupe AT astro.psu.edu). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/too.html.)
