In the early hours of February 24th I shoveled a work area out of the snow on my front lawn, set up my telescope and camera, and photographed Comet Lulin as it passed near Saturn. The spikes on brilliant Saturn in the upper left were caused by the lens aperture during the 8 minute exposure. Lulin's green colour comes from fluorescing cyanogen molecules. On this night Lulin was at its closest approach to Earth, roughly 61 million km away. It is now leaving the inner solar system.
