We request a 50 ks NuSTAR and 25 ks XMM-Newton joint observation to perform abroad-band X-ray timing and spectral study of eRASSU J031038.2-73493 anenigmatic object located in the MCB. The high throughput NuSTAR and XMM-Newtonobservations will allow us to perform detailed spectral and temporal analysis ofthe source and reveal for the first time its nature by combining informationfrom optical spectroscopic observation. This is also pivotal in order tounderstand the tidal interactions between the Large Magellanic Cloud and theSmall Magellanic Cloud and trace the history of the Local Galaxy group. [truncated!
