7724 Moroso           Discovered 1970 July 24 by the Félix Aguilar Observatory team at the El Leoncito Station.
For over 30 years Pascuala Moroso (1934-1996) and her husband, Rafael Villalobos (1930-1998), were in charge of the farm where the El Leoncito station was established in 1965. The help and support of the couple were essential during the site search, as well as during the first years of the observatory's operation.
