- When will the Next T CrB Eruption Occur? (iopscience.iop.org)
The first eruption of the periodic nova T CrB for eighty years is anticipated soon, though with an unknown date. A refinement of the future eruption date is investigated. The investigation is based on the combination of the previous eruption dates and on the orbital ephemeris of the binary system, without any hypothesis on the eruption mechanism. It is predicted that the next eruption should appear around 2025 March 27 or November 10, or later.
- T Coronae Borealis (Wikipedia)
T Coronae Borealis (T CrB), nicknamed the Blaze Star, is a binary star and a recurrent nova about 3,000 light-years (920 pc) away 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. In February 1946 a 15-year-old schoolboy from Wales named Michael Woodman observed a flare up, subsequently writing to the Astronomer Royal and leading to the theory that the star flares each 80 years.
