| Description | An observation of H1426+428 in revolution 278 has turned out to be very instructive for XMM cross calibration, including the OM, as this extreme BL Lac is supposed to display a perfect power-law SED, from the visible to hard X-ray. We propose a longer view on this Rosetta stone target, splitting in two observations because of XMM visibility restrictions, through the THIN and MEDIUM filters and in small windows for all EPICs, with the possibility to change manually to timing mode in the second observation if the target is assessed to be much brighter than in rev 278 in the first observation. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
