(5951) Alicemonet (1973 SJ5,1983 XE1,1986 TZ1) A main belt inner rim asteroid imaged on the first night of the 2022 November talcos. When we photographed comet C/2021 Y1 (ATLAS), this was included in the pictures. The Flora family asteroid was discovered by the American astronomer Edward LG "Ted" Bowell (b.1943) at the Anderson Mesa station of the Lowel observatory (699) on October 7, 1986. The asteroid is named after the American astronomer Alice K. (Babcock) Monet (b.1954). He was an astronomer at the Flagstaff Station of the US Naval Observatory and past chairman of the Dynamical Astronomy Section of the American Astronomical Society.
