Vetere (PSU)\nreport on behalf of the Swift Team:\n\nAt 2007-02-27 22:21:59 Swift-BAT detected GRB 070227 (trigger 262347). \nThe burst was not found automatically onboard, because a planned \nslew terminated the trigger prematurely. The burst was found later \nin ground analysis. Swift did not slew to the burst, and a target \nof opportunity observation for this burst will be uploaded at \nthe next command opportunity (around 1400 UT). \n\nThe BAT position is RA, Dec 120.566, -46.305 (J2000)\n  RA:  +08h 02m 16s\n  Dec: -46d 18' 17\"\nwith an estimated error circle of 3 arcmin. The burst was \nin the extreme partially coded field of view, the coding \nwas 3.4%. \n\nThe burst as seen by BAT was a single peak at least 8 seconds \nlong. We have detailed information for only T-2 to T+8 sec. \nSince the burst was weak and on the edge of the FOV, and\nbecause of the subsequent slew, we can not determine if \nadditional emission occurred.",
