Abstract

During INTEGRAL observations of the Galactic Center region performed between 2014 October 18 UTC 16:43 and Oct. 20 UTC 18:36, the JEM-X monitor has detected the transient source and X-ray superburster SAX J1747.0-2853 in a new outburst. The last time this source has been seen in outburst was in February 2012 (see, e.g., ATels #3183 and #3930).
The measured fluxes are:
14 ± 1mCrab between 3-10 keV and 3.5 ± 2mCrab between 10-25 keV.

In the same observation the new source IGR J17454-2919 (ATels #6530) and likely black hole candidate (ATel #6574) is also seen about a factor two brighter compared to previous observations at the following fluxes:
10 ± 1mCrab between 3-10 keV and 15 ± 2mCrab between 10-25 keV.
