Abstract	One of the first Swift-BAT AGN observed by {it NuSTAR} was the heavily-obscuredSy2 galaxy IC 751. Additional NuSTAR observations have shown that the object.sabsorption varies dramatically (virgul0.7-3.3e24 cm-2), such that IC 751 may be amore obscured version of the changing-look.. NGC 1365. IC 751.s variablenature could portend the existence of a significant population of such objects.Notably, however, the IC 751 field has no useful 0.5-10 keV spectralconstraints, so we request a modest {it XMM- Newton} observation to characterizeIC 751, as well as two serendipitous NuSTAR-detected objects identified in thesame FOV. This 0.5-79 keV dataset will allow us to constrain the degree ofreflection and contamination present in IC 751, as well as secure NH constraints for the two serendipitous objects.

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.
