We propose a single TOO XMM follow-up observation of the faint hard X-raytransient that will revealed by the ART-XC telescope in the frame of the ongoingall-sky survey. The corresponding program is aimed at studies of the Very FaintX-ray Transients (VFXTs), detected both in X-rays with ART-XC and optics eitherduring public surveys (ZTF, GAIA, etc.) or in dedicated observations. We willsupport this follow-up effort with ground-based optical telescopes of CMO SAIMSU, RTT-150 and AZT-33IK telescopes as well as telescopes of the SAAOobservatory in order to perform spectroscopic and photometric observations. Themain purpose of this proposal and the joint X-ray-optical follow-up program isto constrain physical properties of the binary system and unveil the nature of the compact object.

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.
