| Abstract |
We report on our ongoing Swift monitoring observations of the Galactic center (Degenaar et al. 2015). In the latest Swift observation (obsid: 00095329087), a transient X-ray source is detected in a 0.8 ks observation on MJD 58675.19653 (t_start: 190711 @04:42UT) at a position of RA (J2000): 17h 44m 48.4s (266.20167) Dec (J2000): -29° 07? 28.8?? (-29.124663) 90% Error radius: 2.2?? This source lies approximately 13.4' southwest of Sgr A*. Extracting a spectrum from a circular region (r=18") centered on this source and background from an annular region 28"-37" from the source position, we measure a net count rate of 0.19+/-0.05 ct/s.
