19783 Antoniromanya           Discovered 2000 Aug. 27 by J. Nomen at Ametlla de Mar Observatory.
Antoni Romanya (1900-1981) was the manager of the Observatorio del Ebro, in Roquetes-Tarragona, from 1939 to 1970. A tireless researcher in both geophysics and solar physics, he was a very dear and well-loved person in his country.
