The long ion tail observed behind the comet Elenin

August 21st, 2011 |

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.

On October 16, will the sodium tail of Elenin has any effect on Earth?
Maria

It will be visible to the naked eyes?

Hi Leonid! a question, go to the website of Terry Lovejoy and do not find the pictures that is obtaining forC/2010 X1. Please deliver me the link where I can watch?.

Thanks in advance.

  Шn astronomy there is no term as alignment. We use conjunction term.

    You still haven’t answered the question, will the comet be in conjunction with earth around Sept 26/11. Since you like to use Wikipedia, answer this…While the solid nucleus of comets is generally less than 50 km across, the coma may be larger than the Sun, and ion tails have been observed to extend 3.8 astronomical units (570 million km).[2] The observation of antitails contributed significantly to the discovery of solar wind.

      Of course it will be in conjunction in late of September and we will see comet in the LASCO field of view (SOHO spacecraft).

      The nucleus of a comet is generally less than 16km…not 50km

See picture of faint tail on “Elenin” 8/13/2011. Why is Elenin pointing a different direction in this picture by Terry Lovejoy? http://astrobob.areavoices.com/2011/08/15/an-astronauts-perseid-a-prettier-comet-elenin-and-rare-double-conjunction/

  Just another picture orientation, where is problem?

Hi Mr.Elenin:
Are you in agreement with estimates from the comet is looking weaker and could not survive perihelion?. This according to images of 20 and 22 August.

Mean that disappear quickly, and end of history?

Thanks.

  Yes, I saw this estimates by Michael Mattiazzo. Very interesting, but I think comet will survive.
  Perhaps comet suffered a little outburst, because of it’s brightness was growing very rapidly the last few days and we finally see it long tail. Now brightness will return to normal (predicted) values. But this is just assumption.

it is a comet, a normal comet, a mysterious comet for traditional science (or if you prefer …science for common people 😉 )

не подскажите ли (наткнулся в жж):
“1.Заходим сюда http://www.google.com/sky/
2.В левом верхнем углу набираем слово Меркурий.
в появившемся окне видим значок Меркурия.
3.В правом верхнем углу жмем на кнопку “Ифракрасные”.
смотрим на “темное пятнышко со светло-синей серединой и фиолетовым ореолом – левее и выше Меркурия”

что это такое красивое может быть?

Do keep us updated about comet Elenin on your website.

It is very interesting.

Thanks, Mr Leonid.

Nothing in the sky this morning.

Thank you for your updates Mr. Leoni d.

Why comets are visible in X-ray when they are far away from the sun?

  Where source of this information?

Main problem, what you mixed absolutely different values – size of coma and length of tail. Coma was grown to 200 000+ km, very thin ion tail stretch to 3 000 000 km, but this size absolutely normal for comet’s tail.
No, this is a normal comet.

Hale-Bopp was a large and bright great comet. Elenin is an average/small comet.

It is not uncommon for a great comet to achieve a tail of almost 1AU in length. But Elenin is not a great comet.

How can this be real when it is really located near the sun and can not be seen at night

  Comet is visible from South hemisphere, but now, very low above horizons. Soon we can’t see it from the Earth until Ocrober.

Elenin is definitely a comet……when you are talking about the length of the tail you are getting confused with the coma and tail of the comet which are 2 different things.

The coma or atmosphere of the comet was estimated at one stage to be 200,000 km while the tail is estimated at about 4.8 million km long.

Perhaps, comet will be visible on images from SOHO spacecraft.

No any ion tail, comet is disintegrated.
