TITLE: GCN CIRCULAR NUMBER: 17685 SUBJECT: Swift GRB150402A: further XRT observations DATE: 15/04/10 14:36:49 GMT FROM: Massimiliano de Pasquale at IASF-Palermo M. De Pasquale (INAF-IASF Palermo) and H. Krimm (CRESST/GSFC/USRA) Further 9.9 ks of XRT observations of GRB150402A (Cummings et al., GCN circ. 17661), taken between T0+643.2 and T0+673.6 ks, show that the uncatalogued X-ray source detected in the BAT error region (Krimm et al., GCN circ. 17664) is still detected at a count rate of 3.9e-3 ct s^-1, showing no fading with respect to previous observations. We therefore conclude that this source is not the X-ray afterglow of GRB150402A. The 3 sigma upper limit calculated at the centre of the BAT error circle is 3.7e-3 ct s^-1. This circular is an official product of XRT team. I.A.S.F. INAF Mailing System Outgoing mail is certified Virus Free. Checked by Kaspersky anti-virus system
