29P/Schwassmann-Wachman   (Jan to Apr, Oct-Dec  2023)

29P/Schwassmann-Wachmann

29P/Schwassmann-Wachmann went into Outburst in Nov 2022
(see Earlier images of 29P/Schwassmann-Wachmann Outburst in 2022 )
but has since faded significantly and by mid-Jan 2023 it is back to it's pre-outburst brightness

Pictures illustrating that outburst from 2011-12-24 and 2022-12-27 are shown below
