Abstract
PSR B1259-63/SS 2883 is a unique binary system consisting of a 47.7 ms radio pulsar orbiting a massive (10 - 15 M☉) Be companion star. The pulsar orbits the companion star with a period of 3.4 years in a highly eccentric orbit. We have scheduled a coordinated radio, IR, optical, X-ray, and GeV gamma-ray observing campaign for the December 2010 periastron passage. This is the first periastron since the launch of the Fermi Gamma-ray Space Telescope and thus provides for the first time the opportunity to observe the passage of the source through the Be stellar disk at GeV energies with such a sensitive instrument. We will present results from our multi-wavelength campaign....
