Abstract

We report on our ongoing Swift monitoring observations of the Galactic center (Degenaar et al. 2015). In the first Swift observation after the GC exited the solar constraint window, a new X-ray source is detected in a ~ 1ks observation on MJD 57424.87742 (t_start: 160206 @21:02UT), at a position of RA (J2000): 17 45 40.74 (266.41974) Dec (J2000): -29 00 14.7 (-29.00407) 90% Error radius: 2.2'' This lies approximately 16" to the north of Sgr A* and the magnetar SGR J1745-29.
