CT Serpentis
1948 nova in the constellation Serpens
From Wikipedia, the free encyclopedia
CT Serpentis (also known as Nova Serpentis 1948) was a nova that appeared in the constellation Serpens in 1948. It was discovered by Ramze Alexander Bartaya at Abastumani Observatory on 9 April 1946.[5][6] It is thought to have reached magnitude 6.0,[7] but this is an extrapolation of its light curve as it was not observed until 9 April 1948 when it was at magnitude 9.0 and fading—clearly past its maximum.[8]
