Comet C/2012 F6 Lemmon (hereinafter referred to simply as Comet Lemmon) peaked at around 4th magnitude in March 2013, and became an easy binocular object. This article summarises the observations and images made by several observers and sent to the author. Comet Lemmon was discovered on 2012 March 23. The first reported observation by ASSA members was by the author, who observed the comet visually on 2013 January 24, estimating the total cometary magnitude (m1) as 7.5. From then on the comet was reasonably well observed visually and photographically, though by only a few observers, until it became too close to the sun in mid March 2013. The comet was at perihelion on 2013 March 24, and was recovered in the morning sky on 2013 April 9, again by the author, and observed until May 7 when poor weather conditions prevented any further observations. The comet was placed too far north for observation thereafter. Note all dates in this article are in UT.
