TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2695 SUBJECT: GRB 040903 - INTEGRAL data analysis DATE: 04/09/07 07:19:17 GMT FROM: Diego Gotz at IASF-CNR D. Gotz, S. Mereghetti (IASF-Milano), N. Produit and N. Mowlavi (ISDC) report: The analysis of INTEGRAL data reveal no presistent source at the position of 040903 (Gotz et al., GCN 2690) with a 3 sigma upper limit of 10 mCrab. Due to its soft spectrum, we conclude that the burst is either an X-Ray Flash or, due to its location in the Galactic Bulge region, a hard and powerful type I X-ray burst from a new transient source.
