Abstract: We present preliminary results from XMM-Newton/EPIC observations of the nearby globular cluster M22. We have detected 34 low luminosity sources (< 1034.5 erg s-1) in the direction of the cluster, searching down to a luminosity of ≅ 3.0 times 1030 erg s-1. Only seven of these sources have been previously detected by either ROSAT or EINSTEIN. Three sources (two previously undetected) lie within the core radius of the cluster. For the strongest source in the observation we have a spectrum and a light curve. Finally we discuss the nature of this dim X-ray source, in light of these observations.
