The mechanism which starts the process into motion are actually unknown – in spite of what we have been assured by mainstream pontifications. They are, it seems, largely theoretical. What was observed was a brightening at the onset – earlier than expected.

Instead, gas expelled from the centre of the black holes interacts with infalling gas to create a dynamic circulation pattern.

However, we are then told it took 170 million years until February 2017 to detect the light produced by the supernova. What Kepler observer was a minute change in brightness (as in the first link) but ground based telescopes saw this as changes in colour.
