TITLE: GCN CIRCULAR NUMBER: 12255 SUBJECT: Fermi GBM detection of a SGR-like burst DATE: 11/08/08 01:47:36 GMT FROM: Sylvain Guiriec at UAH Sylvain Guiriec (UAH), C. Kouveliotou (NASA/MSFC) and A.J. van der Horst (USRA) report on behalf of the Fermi/GBM Team: "The Fermi Gamma-ray Burst Monitor (GBM) triggered at 23:16:24.91 UT on 7 August 2011 (trigger 334451786 / 110807970) on an SGR-like event, �possibly associated with the source identified earlier by the Swift team �as a new SGR (D'Elia et al. GCN 12253). The on-ground location, using the GBM trigger data, is RA = 279.0, Dec = -5.9 (J2000 degrees, equivalent to 18h36m, -5h52m), �with an uncertainty of 6.3 degrees (radius, 1-sigma containment, statistical only; there is additionally a systematic error which is �currently estimated to be 2 to 3 degrees). The angle from the LAT boresight is 72 degrees. The duration of this event is ~0.1s with little emission beyond 100 keV, �which is typical of SGR bursts. This location is consistent with �the burst detected ~3.3 hours earlier with Swift �(D'Elia et al. GCN 12253), strongly suggesting that the GBM burst �may originate from the same source. However, since this is a very �crowded region which includes 8 SGR sources already, we cannot exclude �as the origin of this event any of the other SGRs, given the large GBM �error box. The results presented above are preliminary. Further follow up observations �are strongly encouraged. "
