This comet can be very nice in the autumn. Almost a sun-grazer. On October 3th it is 19° from the sun in the morning-sky at predicted mag. 0.4. Yes very bright and probably a big tail.

For comparison, comet 12P will be mag. 4.7 under the Solar eclipse of April 8th. And mag. 4.4 on Perihelion, April 21th. Maybe visual expectations for comet 12P is too high. But don't worry, C/2023 A3 can save the year.

Sun distance (au): 3,47 Perihelion : 27.Sept. 2024 Sun distance (au): 0,39
