At 6 degrees altitude the comet, and small portion of tail, was clearly visible with the unaided eye, appearing marginally fainter than comparison stars Alpha Gruis (1.8) and Alpha Pavonis (1.9). In 25x100mm binoculars, the dust tail measured 1.5 degrees in PA165, with the much fainter and shorter type 3 dust trail in PA 205. The ion tail was not visible visually but is at least 2 degrees long in PA155 on a 3 minute exposusure using a canon 60Da camera and 300mm lens]
