Observations of Koronis Family Asteroids during 2017-19 at the Union College Observatory

We discuss the changes that physical and orbital elements of Koronis Family asteroids undergo over a period of time. We obtained images and performed photometry of 1725 CrAO, 3032 Evans, 1835 Gajdariya, 2713 Luxembourg, 1443 Ruppina, and 1497 Tampere using the Union College Observatory throughout the 2017-2019 calendar year. We present light curves for each. Variations in the asteroid brightness are due to rotation on short time scales and the changing illumination and viewing angle due to orbital motion on longer time scale.
