- ALPHARD (Alpha Hydrae). Not all that well known among bright stars, but surprisingly prominent, Alphard both dominates and lies at the heart of the relatively dim constellation Hydra, the Water Serpent (the longest constellation of the sky), hence clearly deserves to be Bayer’s Alpha star.
- 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.
