		<abstract>The longest available observed data of Jupiters magnetosphere are the nonthermal Decametric (DAM) radio emissions, first detected in 1955. It is thought that the mechanism originating those emissions is associated to the Cyclotron-maser instability (CMI) at high magnetic latitudes of Jupiters magnetosphere. The satellite Io creates, through its volcanic activity, a plasma torus around Jupiter and, consequently, a strong electrodynamic interaction occurs between Io and Jupiter. This was inferred after the detection of the control of part of the Jovian DAM by Io, in 1964. The interaction results from the satellite acting as an obstacle to the magnetospheric plasma flow, and, therefore, it is also expected to occur between Jupiter and each one of the other Galilean satellites, but with intensity weaker than for Io.The extense digital catalog from the Nan¸cay Decameter Array (NDA) has enabled the identification of the control of Ganymede (Ga) and possibly Europa (Eu), and also the selection and characterization of the emissions possibly induced by those satellites. Currently, the catalog assembles 29 year of daily observations of the Jovian DAM emission, from 1990 to 2018. In this work the NDAs catalog is studied in order to identify Eu-DAM emissions and their main parameters: intensity, maximum frequency and duration.</abstract>
