Description AO 0235+16 is a distant BL Lac object. The analysis of the long-term radio and optical light curves revealed a quasi-periodicity on about 5.7 yr. The next outburst is foreseen to peak around February--March 2004. Moreover, short-term variability has been detected at radio and optical frequencies as well as in an archival XMM observation. The aim of the present proposal is to study this source variability on both long and short time scales in the radio, optical, UV, and X-ray bands, with the joint effort of the Whole Earth Blazar Telescope, the Effelsberg radio telescope, and XMM. This would allow to recognize correlations and possible time delays between changes at different frequencies, and hence to put strong constraints to the theoretical models.

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.
