A little more background coverage on Comet SWAN at these two sites: http://antwrp.gsfc.nasa.gov/apod/ap061004.html and http:// cometography.com/lcomets/2006m4.html I have observed Comet SWAN twice: the evenings of Oct 19 and Oct 27. In binoculars I did not see the view that is shown in the photo at the links given above (taken through a 250 mm camera lens compared to my 50 mm binoculars funneling light into my eyeball). My telescope views showed some detail of a tail and the bright centre surrounded by the large coma, however, my retinal rod cells could not pick up the greenish glow that photographic equipment can record. Oct SWAN was abou 6th magnitude, Oct 27 it had brightened to 5th mag. However a few days prior to the 27 there was an outburst on the comet that caused it to briefly brighten o near 4th magnitude, but there were no clear skies in N.S. on those nights. Cheers and wishes for a clear sky tonight, Sherman Sherman Williams sherm@glinx.com website: http://www.glinx.com/~sherm
