The Eta Aquarids meteor stream has a medium activity and its origin is cometary. Their parent body is the comet Halley. The stream occurs in the first days of May and the maximum of activity occurs in the days from 5 to 7 April. The Eta Aquarids were studied in 2013 using radio observation. The radio data were obtained using the meteor scatter techniques. The data were taken from the RA.M.BO. project. The purpose of this analysis is the definition of main characteristics of the stream. The solar longitude of the maximum of the activity is λ0 = 45.61° ± 0.02°.
