Through December 2014 - mid January 2015 it was very well-placed for southern hemisphere observers as it was closest to Earth (closest approach on 7/1) and approaching perihelion (30/1/15). Around the time of closest approach to Earth it became visible to the naked eye from dark sky areas.

|Photographed under dark skies north of Heathcote, Victoria, against the stars of Aries on 2015 January 21 when around 4th magnitude. A wider angle view was used to gauge the tail's extent which was clearly beyond the Pleiades (12+°). Last exposures were taken when trees started to extend into the field of view.
