TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3649 SUBJECT: GRB 050714a: Refined XRT analysis and afterglow confirmation DATE: 05/07/19 19:59:34 GMT FROM: Tim Roberts at Leicester U/BA T.P. Roberts, K. Page, A. Beardmore (U. Leicester), J.L. Racusin, J.A. Kennea (PSU), N. White (GSFC), D. Hinshaw (GSFC-SPSYS) report on behalf of the Swift XRT team: We have re-analysed the complete Swift dataset from the TOO observation of the INTEGRAL-detected GRB050714a (see GCN circ. 3610), beginning 13.7 hours after the burst. The new refined coordinates of the afterglow candidate are: RA(J2000) = 02 54 22.2 Dec(J2000) = +69 06 46 We estimate an uncertainty of 6.9 arcseconds on this position (90% containment). However, we were unable establish from this data whether the source was definitely fading due its low count rate. Swift began a second observation of this GRB at 00:05 UT on 19th July 2005 (5.0 days since the burst event). In 9.7 ks of data we do not detect the candidate afterglow. Hence we confirm that the behaviour of the X-ray source identified in our first circular is consistent with it being the afterglow of GRB 050714a.
