LS 5039 is an unusual high mass X-ray binary that also exhibits γ-ray emission modulated with its orbital period. The system consists of an ON6.5V((f)) star and an unidentified compact companion. Using the Australia Telescope Compact Array (ATCA), we have measured radio fluxes at 20cm, 13cm, 6cm, and 3cm between 2008 February and 2009 July. We have observed the Hα line with the Goodman High Throughput Spectrograph on the Southern Astrophysical Research (SOAR) telescope from 2010 June 2-4. Here we combine these multiwavelength data to examine the structure of the massive star wind....
