American Association of Variable Star Observers (AAVSO) - Sometime between now and September, astronomers are predicting a "new star" in Corona Borealis (the Northern Crown, a small but distinct constellation wedged between Bootes and Hercules).
T Coronae Borealis (T CrB) last erupted on February 9, 1946, and in its next apparition, the normally staid 10th-magnitude star should brighten to 2nd magnitude for a few days.
As a recurring nova with an 80-year cycle, hundreds of AAVSO observers have been following T CrB faithfully for decades and are continuing to do so.
T CrB's next eruption is triggering lots of anticipatory buzz.
