Abstract	CAL-The primary goal of the observation of the white dwarf LBB 227 is toestablish the zero point calibration of the UV filter. Secondary calibrationitem is the measurement of the instrument PSF in the UV filters, which isaccomplished by placing a fast mode window on the white dwarf. The target countrate and the PSF shape is studied under different window sizes. Initially thebasic characteristics of the grism are measured, which are the position of the 0and 1 order spectra and a coarse wavelength scale calibration. In laterobservations deeper grism exposures are aimed to measure throughput and PSFshape. The estimated OM overhead time is: 5.4/3.1 ksec for initial/follow upobservations.

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.
