TITLE: GCN CIRCULAR NUMBER: 20414 SUBJECT: Trigger 731535: Swift detection of GRS 1716-249/GRO J1719-24/V2293 Oph DATE: 17/01/10 08:35:59 GMT FROM: Boris Sbarufatti at INAF-OAB/IASFPA P. D'Avanzo (INAF-OAB), A. Y. Lien (GSFC/UMBC) and B. Sbarufatti (INAF-OAB/PSU) report on behalf of the Swift Team: At 08:02:13 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRS 1716-249/GRO J1719-24/V2293 Oph (trigger=731535). Swift did not slew because of Sun constraint. The BAT on-board calculated location is RA, Dec 259.889, -25.015 which is RA(J2000) = 17h 19m 33s Dec(J2000) = -25d 00' 53" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve does not show anything significant, as it typical for image triggers. Due to a Sun observing constraint, Swift cannot slew to the BAT position until 2017 January 27. So there will be no XRT or UVOT observations until then.
