SN2025rbs
On August 7, 2021, ASAS-SN reported the discovery of a cataclysmic variable, classified as AT2021vfg.
As we can see after consulting multiple surveys, at that point where now shines a star with magnitude 14.5, there is almost no trace of anything (it is intuited in some a very weak star, which could be the precursor).
