Abstract
Our daily Swift/XRT monitoring observations of the Galactic center (Degenaar et al. 2015) have revealed activity of a transient X-ray source located ~1.4' to the north-east of Sgr A*. An excess of photons was first seen during a 0.9-ks PC mode observation performed on 2016 July 7. The object remains to be detected in subsequent observations performed on July 8,9, and 10. To obtain a position for the newly active X-ray source, we use the four PC-mode observations obtained between July 7 and 10 (amounting to 3.5 ks of exposure time) and utilize the online XRT data products tool (Evans et al. 2007, 2009).
