Hubble observations obtained in recent years indicate the existence of water vapour plumes originating from the surface of Jupiter's moon Europa. The first opportunity to study these plumes in-situ will arise when ESA's JUICE mission or NASA's Europa Mission will arrive there. However, it has been suggested that the past Galileo mission could have encountered these plumes already. In particular it has been suggested that high plasma densities and anomalous magnetic fields measured during the E12 flyby could be linked to plume activity. Here we present an overview of Galileo in-situ data obtained during the Europa flybys and compare the data in the context of the search from Europa plumes. Focus is in particular on the data obtained with the plasma instrument PLS.
