T Coronae Borealis is expected to perform one of its recurring novas between February and September of 2024.
T Coronae Borealis is a binary system with a white dwarf and red giant. About every 80 years the red giant will shed its outer layers and the white dwarf collects them. At a certain point the white dwarf eventually gathers enough matter until a thermonuclear explosion occurs, which is the nova we see. It's expected to do so again because the star has been noticing to dim, which is usually the precursor to it going nova.
This system is one of 10 recurring nova systems that is currently known of.
It's about 3000 light years from Earth and is not able to be seen with the naked eye, but when it does go nova you will be able to see it for several days with the unaided eye, and for about a week with binoculars. It will be about as bright as Polaris.
For those interested in trying to catch it, you need to become familiar with the constellation Corona Borealis, or the Northern Crown. This is a small, semicircular arc near Bootes and Hercules. Once you get a good idea of how it normally looks, when T Coronae Borealis goes nova, you should then easily be able to notice it.
