Something visible to the naked eye under good viewing conditions is common. C/2022 E3 (ZTF), C/2021 A1 (Leonard), NEOWISE in 2020, C/2019 Y4 (ATLAS) - around one per year based on this small data sample. NEOWISE reached magnitude 1, making it visible even with pretty bad viewing conditions.

Thanks for the info. As I was replying I got to thinking there must be a DB that has the info like number of comets, periods, magnitudes, etc.

Be interesting to take a peek.
