Marshall (NASA/GSFC), D. M. Palmer (LANL) and M. H. Siegel (PSU)\nreport on behalf of the Swift Team:\n\nAt 13:35:37 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 140628A (trigger=602803).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 40.661, -0.366 which is \n   RA(J2000) = 02h 42m 39s\n   Dec(J2000) = -00d 21' 58\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single-peaked\nstructure with a duration of about 10 sec.  The peak count rate\nwas ~2500 counts/sec (15-350 keV), at ~1 sec after the trigger. \n\nThe XRT began observing the field after coming out of SAA mode at \n13:39:40.3 UT, 243 seconds after the BAT trigger. No source was \ndetected in 20 s of promptly downlinked data. We are waiting \nfor the full dataset to detect and localize the XRT counterpart. \n\nUVOT took a finding chart exposure of  48 seconds with the White filter\nstarting 278 seconds after the BAT trigger. No credible afterglow candidate has\nbeen found in a partial 2.7'x2.7' sub-image. Results from the list of sources\ngenerated on-board are not available at this time. \n\nBurst Advocate for this burst is E. Sonbas (edasonbas AT yahoo.com). \nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/too.html.)",
