oDoug, I wondered too about the collision/impact scenario. (Deep, DEEEEEEEP Impact!!) However, it's at a relatively high inclination from the plane of the ecliptic, which would somewhat reduce the probability of collision. Also, it's very interesting that Holmes displayed a similar outburst when it was discovered in 1892 and again in early 1893. Very strange object!

Two friends made a cool picture + spectrum of the comet from L'Aquila (Italy):
http://quasar.teoth.it/gallery/albums/user...17P_28ott07.jpg Consider that, in reality, the external green halo is a lot less luminous than yellow one and image dynamic was somehow compressed in order to see it. The emission Hg row is due to terrestrial light pollution. Image was published also by a german site dedicated to comets I encouraged the friends to submit the picture to APOD and Spaceweather. -------------------- I always think before posting! - Marco -
