After 1908 the comet became an unobservable lost comet, but on December 7, 2001, an object was found by the Lincoln Near-Earth Asteroid Research (LINEAR) program, and confirmed by previous images from September 10 and October 17 as being the same comet.[4] The comet was not observed during the 2008 unfavorable apparition[2][1] because the perihelion passage occurred when the comet was on the far side of the Sun. The comet was observed during the 2014 and 2020 apparitions.[1]
