12P/Pons–Brooks (English Wikipedia)

JPL Horizons ephemeris generated by JPL K242/30 (soln.date: 2023-Jul-29) has 12P/Pons-Brooks coming to perihelion at 2024-Apr-21 03:16 which is about 2 hours later than "Kinoshita's 2003 solution". of 00:55.
The Minor Planet Center's unperturbed two-body solution (epoch 2024-05-10) gives a less accurate date of 2024-04-20.47.
JPL SBDB (using epoch "2010".) gives an even less accurate unperturbed date of 2024-Apr-19.89.

When a comet increases its apparent magnitude with a difference between 2 and 5 magnitudes (equivalent to a brightening of 6 to 100 times) the event is called an "outburst". Bibcode:1975QJRAS..16..410H.
One of the more extreme example of a cometary outburst is comet 17 P / Holmes' November 2007 brightening by about 15 magnitudes (nearly a millionfold), described in:
