We propose to perform 25 ksec NuStar and 20virgulksec XMM-Newton observations ofgamma-ray binary HESS J)632+057 prior to its high state in 2018. We aim todetect the break in the spectral slope of the system as the compact objectapproaches the disk of Be star. The detection of the break in X-ray synchrotronspectral component will allow to test the physical model of the source and makepredictions for the position of GeV-TeV break, which could be tested withHESS/MAGIC data.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
