Passing of Spanish Navy Observatory researcher Dr. Manuel Catalán Morollón Release Date: 01/12/2024
We are sad to report that Spanish Navy Observatory researcher Dr. Manuel Catalán Morollón passed away on December 12 after a bout with cancer. Dr. Morollón, as leader of the San Fernando SLR Station, spearheaded the recent modernization of the SLR system to improve performance. He was a very active researcher in several Earth Science disciplines; he was dedicated to his work and remained active right up until the end. He was a strong supporter of ILRS and a good friend. He will be greatly missed.
