The countertail at the tip of the comet's head is interesting. This is a projection phenomenon and can only be seen for a short time. The countertail is actually the end of the dust tail. Here Uwe Pilz explains the physics behind the countertail phenomenon in an easy-to-understand manner.

After what felt like an eternal period of clouds, C/2023 A3 (Tsuchinshan Atlas) finally became visible shortly after sunset on October 15, 2024. Beautiful and without optical aids. My 8x42 binoculars still brought some brightness, but of course the comet didn't fit into the image field.
The Canon clicked away on its fidget tripod and after some editing, this image came out with some interesting by-catch.

mages from the LASCO C3 of the SOHO probe from October 7th, 2024 / 06:50 UT - October 15th, 2024 / 6:30 UT.
The comet flies approximately halfway between the SOHO probe (relatively close to Earth) and the sun.
Still visible: The bright point of light on the left is the planet Mercury.
The bright outbursts from the evening of October 7th. caused strong auroral activity here on Earth up to mid-latitudes. See AllSky Timelaps vom 10.10.2024.
