Nov. 19 image obtained by Pau Montplet from Breda (Girona) using a C6 telescope at f:7. Original image is in the lower right inset, while a false color 0.6º wide Larson-Sekanina filtered image at 9º shows 3I in negative to remark the antitail pointing to the subsolar point, and several jets getting out from the false nucleus. Two additional arrows mark wavy structures in the jets. Image resolution is 0.7 arcsec/pix. Credit: arXiv (2025). DOI: 10.48550/arxiv.2511.19112
