Description The BL Lac object OJ 287 (z=0.306) is a highly variable blazar showing pseudo- periodic outbursts every 11-12 years, and monitored in the radio-optical bands since many years. We propose here one further (4th) EPIC-pn observation of OJ 287 as continuation of our long-term multifrequency programme to be performed in these important years for the source, aiming to observe the X-ray and MW behaviour of OJ 287 in different brightness stages and possibly during the next expected outburst. Ground-based multifrequency campaigns and monitoring are already ongoing (thanks also to the WEBT consortium), joint with VLBA-VLBI 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.
