Elinen looks like it may be similar in apparent presentation from SLC, but less brillant than, Comet McNaught of a few years ago. On September 10, 2011 in SLC, C/2010 X1 Elenin will be close the western horizon and visible just after the Sun sets. Currently the comet is at mag 16. - Clear Skies - Kurt
