29P/Schwassmann-Wachmann went into an outburst sometime around January 14, 2021.
The French comets web site is at https://lesia.obspm....omets/index.php
clicking on "Afficher les observations" brings up an extensive online table of comet observations and images.
Francois Kugel and J. F. Soulier have posted images and observations showing the change in magnitude from about 17.3 the day before to at about 2021 01 13.7 to 14.9 one night later at about 2021 01 14.7
The object has begun to show a typical expansion disk.
The french site has a nice online feature for plotting magnitudes for each comet. Nuclear magnitude plots for 29P show the characteristic decline in brightness following an outburst. I attached a plot showing a portion of the timeline back a year and a half showing how this outburst compares with others.
Members from the BAA comets group about the outburst on the comets-ml mailing list
29P has always been one of my favorite objects to observe and study. I hope that other comet observers can make reports about it here.
I hope to also observe it soon from H47.
