V462 Lupi, also known as Nova Lupi 2025,[3] is a bright nova in the constellation Lupus discovered by All Sky Automated Survey for SuperNovae (ASAS-SN) on 12 June 2025.[1] At the time of its discovery, it had an apparent visual magnitude of 8.7.[1] It was classified as a classical nova on 14 June 2025.[4]
By 18 June 2025, it had brightened to magnitude 5.7, making it just visible to the naked eye.[6] The peak brightness, magnitude 5.5, was reached on 20 June 2025.[7]
All novae are binary stars, with matter from a "donor" star accreting onto a white dwarf. In the case of V462 Lupi, the orbital period is 1.797 hours.[7]
