TITLE: GCN CIRCULAR NUMBER: 10483 SUBJECT: IBAS Alert 5992 is not a GRB, but XTE J1855-026 DATE: 10/03/14 20:17:33 GMT FROM: Sandro Mereghetti at IASF/CNR S.Mereghetti, A. Paizis, (IASF- Milano), D.Gotz (CES-Saclay), E. Bozzo, C. Ferrigno, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: at 19:04:25 UT of March 14, IBAS triggered on a source at coordinates RA: 283.871338 [degrees] DEC: -2.609381 [degrees] these are consistent with the position of the high mass X-ray binary XTE J1855-026. The event that caused the trigger is visible only in the low energy range 15-40 keV and lasts several tens of seconds. We conclude that the IBAS Alert is not due to a GRB but it is most likely due to this galactic source. This message can be cited.
