Kepler will observe OJ 287 with 1 min sampling for virgul75 days in 2015, providingan unprecedented opportunity to quantitatively compare optical and X-rayvariations in one of the brightest and most active blazars in the sky. Werequest one XMM-Newton revolution and 90 x 1 ks Swift visits as part of a largecampaign that also includes simultaneous radio and multi-color opticalmonitoring. These data will be used to determine the interband X-ray/opticalcross-correlation with the highest temporal resolution yet obtained. Measuringan interband lag would allow us to test inverse Compton models and determinesource parameters. We will also compare the Kepler optical power spectraldensity function (PSD) of flux variations with the X-ray PSD from combined Swift/XMM-Newton data.

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.
