4298 Jorgenúnez           Discovered 1941 Nov. 17 by I. Polit at Barcelona.
The main research interests of physicist and astronomer Jorge Núnez (b. 1953) are robotic observatories and the treatment of astronomical CCD images, an area to which he has contributed many refereed papers. Since 2002 he has been a member of the Royal Academy of Sciences and Arts of Barcelona.
