Abstract. On 10th December 1999, the European X­ray satellite XMM, now called XMM­Newton, was successfully put into orbit. After initial commissioning of the satellite's subsystems, the EPIC­pn camera was switched on and tested thoroughly in the period Jan./Febr. 2000. After refining of some of the parameter settings and the on­board pn­computer programs, we started the Calibration and Performance Verification Phase, which will last until the end of May 2000.
In this paper we report on the results of the EPIC­pn Commissioning Phase with respect to the in­orbit performance of the camera. We also show some of the early results with the pn­camera, the first light image of a region in the Large Magellanic Cloud, and an observation of the Crab Nebular.

Key words: XMM­Newton, pn­CCD, X­ray detector
