Description
Here we report our preliminary X-ray observations of the Microquasar V4641 Sgr. No eveident X-ray emissions are detected from this binary, but faint diffuse X-ray emissions are discovered spatially coincident with the $\gamma$-ray source in the north. We will discuss the physical origin of this diffuse X-ray structure including a PWN or an extended jet like SS 433. With a broadband SED fitting, we derived a very low magnetic field assuming a single-zone model. The extremely low magnetic field may allow UHE electrons to transport without effective synchrotron cooling.
