Both RGS instruments were cooled and recalibrated in November 2002 usingMkn421 as reference source of bright smooth continuum to illuminate thewhole bandwidth of the detectors. Mkn421 becomes visible again in May2003 when it should be observed again in two long exposures to verify theresponse of the entire detector assembly in a way which is not possiblewith the line-rich SNR calibrators such as N132D, which have weak continua.

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.
