5386 Bajaja           Discovered 1975 Oct. 1 by the Félix Aguilar Observatory team at the El Leoncito Station.
Esteban Bajaja (b. 1931) was in charge of the installation and operation of the first radio telescope in Argentina, thus becoming one of the first radio astronomers in his country. One of his main contributions to the field was the observation of HII regions in the southern hemisphere.
