I have just imaged 12P remotely from Nerpio, Spain using an ASA 10" scope.
Within r=9" the comet has brightened by about 0.5 mag within last two
days. I have used a green filter, so the brighness is not directly
comparable to the red or unfiltered observations.

2024-02-01.79, m(9)=11.60
2024-02-03.79, m(9)=11.07

Anyone else can confirm this?
