TITLE: GCN CIRCULAR NUMBER: 20405 SUBJECT: Trigger 731257: Another Swift-BAT detection of GRS 1716-249/GRO J1719-24/V2293 Oph DATE: 17/01/09 15:15:20 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC), D. N. Burrows (PSU), S. B. Cenko (GSFC), P. D'Avanzo (INAF-OAB), J. A. Kennea (PSU), A. Y. Lien (GSFC/UMBC), A. Melandri (INAF-OAB), B. Sbarufatti (INAF-OAB/PSU) and R. L. C. Starling (U Leicester) report on behalf of the Swift Team: At 14:40:45 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRS 1716-249/GRO J1719-24/V2293 Oph (trigger=731257). Swift did not slew because of Sun constraint. The BAT on-board calculated location is RA, Dec 259.901, -24.998, which is RA(J2000) = 17h 19m 36s Dec(J2000) = -24d 59' 50" 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 (duration is 11.9 min in this case). Due to a Sun observing constraint, Swift cannot slew to the BAT position until 13:53 UT on 2017 January 27. There will thus be no XRT or UVOT data for this trigger before this time.
