GCN Circular 17367
S. D. Barthelmy (GSFC), N. Gehrels (NASA/GSFC), K. L. Page (U Leicester) and T. N. Ukwatta (LANL) report on behalf of the Swift Team: At 21:14:18 UT, the Swift Burst Alert Telescope (BAT) triggered on likely 1RXS J180408.9-342058 (trigger=629206). Swift did not slew because of Sun observing constraint. The BAT on-board calculated location is RA, Dec 271.033, -34.312 which is RA(J2000) = 18h 04m 08s Dec(J2000) = -34d 18' 42" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). As is typical for image triggers (20 mins), the BAT light curve shows nothing in the TDRSS real-time light curve. Due to a Sun observing constraint, Swift cannot slew to the BAT position until 00:23 UT on 2015 February 06. There will thus be no XRT or UVOT data for this trigger before this time.
