Stroh (PSU) report on behalf of the Swift Team:\n\nAt 06:21:17 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 070612B (trigger=282073). \nThe BAT on-board calculated location is \nRA, Dec 261.713, -8.719 which is \n   RA(J2000)  =  17h 26m 51s\n   Dec(J2000) = -08d 43' 06\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showes a single peak\nwith a duration of about 20 sec.  The peak count rate\nwas ~2000 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nBecause of an Earth limb constraint, the spacecraft did not slew promptly\nto the BAT position, and so there are no immediate XRT or UVOT data \nproducts to analyze.  XRT and UVOT will begin observing this target\nat 07:13 UT.",
