V1935 Centauri, also known as Nova Centauri 2025, is a bright nova in the constellation Centaurus discovered by John Seach on 22 September 2025.[1] At the time of its discovery, it had an apparent visual magnitude of 6.2, which is just invisible to the naked eye.[1]

Fermi detected gamma-rays prior to the discovery at the September 21.50-21.75 bin.[3] Swift observed the Nova on 2025-09-23.64 and detected a bright source of hard x-rays at the position of the nova. The early detection might indicate a symbiotic nature of the host binary system. Alternatively the nova may be unusually fast in clearing up its ejecta.[4]
