Abstract
We present optical spectroscopy and infrared photometry of the Be/X-ra y binary system LSI+61 degrees 303 obtained simultaneously with the ra dio and high-energy observations reported elsewhere in these proceedin gs. Whilst the observations do not cover a sufficiently long timebase to disentangle uncorrelated and correlated behaviour, we do find evide nce for variations in both the Palmer hydrogen line emission and infra red photometry from night to night during the observations.
