Abstract We report on ongoing daily X-ray monitoring observations of the Galactic center with the Swift/XRT (ATel #5006; see link below). In addition to continued activity of the magnetar SGR J1745-29 (ATels #5009,#5016, #5020, #5032, #5037, #5046, #5053; Kennea et al. 2013; Mori et al. 2013), a transient X-ray source located ~1.5 arcmin south-east of Sgr A* has become active. This object is first detected during a ~1.0 ks PC mode observation performed on 2013 July 18, at a net count rate of ~1E-2 counts/s.
