What characteristic makes the expected T CrB eruption easily visible to the public?
Answer
Reaching an apparent magnitude of around 3, easily visible under dark skies.
The anticipation surrounding T Coronae Borealis centers on its expected visual impact as a bright, naked-eye event. Once the eruption occurs, T CrB is projected to brighten to an apparent magnitude of about 3. Objects at magnitude 3 fall well within the range of visibility for the unaided human eye, provided the observer is viewing from an area with dark skies, free from significant light pollution. This characteristic means that the confirmation alert for the nova will translate almost immediately into a visible celestial display for sky-watchers across the globe, distinguishing it from fainter transient events.
