How quickly are modern transient events like T CrB monitored events confirmed compared to historical supernovae?
Answer
Confirmation often happens within hours or days.
Modern technology and the sheer volume of dedicated instruments focused on transient celestial phenomena have drastically reduced the confirmation timeline for recent events compared to historical records like Kepler's Supernova. Because thousands of professional and amateur eyes are tracking systems like T CrB and unexpected detections are being made, the collective monitoring effort ensures that once an event begins to unfold, confirmation of the transient nature—whether it is the expected nova or an unexpected superkilonova candidate—is frequently achieved within mere hours or days of the initial visual or instrumental detection.
