T Coronae Borealis (T CrB), nicknamed the Blaze Star, is a recurrent nova in the constellation Corona Borealis. It was first discovered in outburst in 1866 by John Birmingham, though it had been observed earlier as a 10th magnitude star. It may have been observed in 1217 and in 1787 as well. It is expected to undergo an outburst again very soon possibly in 2025, maybe in 2024, and almost certainly before the end of 2026. (from Wikipedia)
