- "Blaze Star" as a nickname for the recurrent nova T CrB has occurred in magazines since 1866. At that time, the physics of novae and supernovae was yet unknown, and the eruption of T CrB in 1866 was actually the first time of a naked-eye transient with spectroscopic evidence for hydrogen in the emission nebula. Recurrent Novae are a rare type of stars; only ten Galactic objects are known. T CrB is the prototype of T CrB-type recurrent novae which are contact binaries composed of a white dwarf orbiting a red giant.

In everyday life
- At magnitude 10.2 it is fainter than the naked-eye limit (about 6) — you need binoculars or a telescope.
- Declination 25.9° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
- Its IAU name «Blaze Star» comes from English (IAU Working Group on Star Names).
