T CrB Eruption Found in Medieval Manuscript

The recurrent nova T CrB is likely to erupt again in the early spring of next year. This nova has an $\approx 80$ year long cycle and only lasts for about a week, making it an extremely rare event to catch. Thus, it’s no surprise that we only had reliable records for the two most recent eruptions.

But research from Dr. Bradley Schaefer indicates that there may be two historic accounts of this star during its eruption including one in a medieval chronicle.

I’ve written more about this research over at Universe Today.
