TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2793 SUBJECT: IBAS GRB Alert # 2010 DATE: 04/10/09 16:09:36 GMT FROM: Diego Gotz at IASF-CNR D. Gotz & S. Mereghetti (IASF-Milano) on behalf of the IBAS Localization Team, N.Mowlavi and J. Soldan (ISDC) report: IBAS Alert number 2010 corresponds to a 40 s long burst detected in the 15-100 keV energy range. Its refined coordinates are (J2000) R.A. = 17h 40m 43s Dec. = -28s 07' 32'' with an uncertainty of 2.5 arcmin. Due to the fact that this position is consistent with the X-ray source SBM2001 10 (SIDOLI L., BELLONI T., MEREGHETTI S., Astron. Astrophys., 368, 835-844 (2001)), and that its preliminary spectrum is soft, it is unlikely that this is a GRB. Nevertheless further observations are encouraged. This message can be cited.
