Interpretation of surface features of Europa obtained from occultations by Io

Light curves of occultations of Europa by Io have been used to generate a crude map of abledo features on Europa. The best values currently available for the impact parameters and magnitude ratios for each event have been imposed on our model. Residuals between the observed and computed light curves are interpreted as albedo features on Europa. In order to improve the fit between the observations and the model it became necessary to impose a general polar brightening. The effects of additional albedo features and alternate models are discussed.
