The long ion tail observed behind the comet Elenin

T. Lovejoy

On the picture taken by the well-known Australian astronomy amateur, Terry Lovejoy, which discovered his comet in 2007, is clearly visible long and thin ion tail stretching almost one degree! Which corresponds to the length of the tail is more than 3,000,000 km! Although this is not a record, the sodium tail of comet Hale-Bopp had a length of nearly 50 million kilometers! Comet Elenin will pass closest to the Earth on October 16 at distance about 35 million kilometers from our planet.
