C/2023 A3 (Tsuchinshan-ATLAS) during twilight this evening. The two brightest stars here are 110 and 109 Virginis (upper/lower), at mags. +4.4 and +3.7, respectively. The nucleus was a little brighter than 109, so somewhere around +3 without atmospheric extinction. Tail again >5° in photos, but visually was more like 2-3°.
