Between September 2006 and January 2007 the galactic binary source LS I +61 303 was observed at TeV energies by the VERITAS array of Cherenkov imaging telescopes in Southern Arizona. During this time, contemporaneous observations were taken at X-ray energies by both the SWIFT and RXTE satellite experiments. Although the X-ray properties of this source have been well studied in the past, this will be the first multiwavelength study on this source to use both TeV and X-ray data. Here we present the results of all three sets of observations, including TeV and X-ray spectra during flaring states as well as a comparison of the light curves obtained in each band over several orbital phases.
