During the 2004 perihelion passage the comet brightened to about apparent magnitude 11.[9] The comet was not observed during the 2011 unfavorable apparition since the perihelion passage occurred when the comet was on the far side of the Sun.
On 2049 April 2 the comet will pass about {{convert|0.011|AU|km mi|abbr=on|lk=on}} from Mars.[10]
