Первые радио наблюдения кометы Еленина

Американские радио астрономы сообщают о том, что в ходе наблюдения кометы Еленина, ими не обнаружено испарение воды из ее ядра. Эми Ловелл (Amy Lovell) провела семичасовые наблюдения кометы, 7 сентября, на радиотелескопе Грин Бэнк (Green Bank Telescope, в настоящий момент комета не доступна для наблюдения из Аресибо) и не обнаружила линий гидроксида (OH) выше уровня шума в 2.4 мЯн. Это говорит о том, что текущая газопроизводительность кометы менее 10⁷ молекул/секунду, что примерно в 100 раз меньше предсказанного ранее значения. Эти данные могут говорить в поддержку мнения о распаде кометного ядра, начавшегося в середине августа. Следующие радио наблюдения могут состоятся в октябре на обсерватории Аресибо, конечно если мы все же увидим комету на снимках с космического аппарата SOHO.

Hi Robert, Im not entirely sure but i dont think so. Apparently the distance at its closest point to earth will be 22 milion miles away and (if) anything i think maybe Elenins tail is 3 milions miles long (please correct me) So not sure it is possible! Can someone clarify?

Wikipedia has an article, including comments on the earthquake claims:

According to Michael Mattiazzo

http://www.newscorners.com/latest-image-of-comet-elenin/

The comet is pictured through a different filter to enhance the coma therefore has not faded. Please can you post some pictures of the comet as presently appears. Many thanks for all your exemplary work .

Comet is history. Newer photos from Michael here :

the blog is in portuguese, but photos can show clearly that comet has gone.

The image you refer to is not comet elenin but a carbon star called CW Leonis.

Comet Elenin is not visible on Google Sky, Wiki Sky or Microsoft Worldwide Telescope.

I not have recent detailed images, comet not visible from the Earth at this time.

Comet, or it debris may be visible for large telescopes. Perhaps we will see something by medium telescopes with CCD cameras.

absolutely not! that’s garbage! nothing will happen! where did you read that?

Dear all, we need more data, let’s wait for some time.

Dear Mr Elenin
The problem is, people are still scared. The web is full of information about comet Elenin being a danger to earth. I appreciate that we need more data — but there are many contradictions including your answers about whether the comet has started to disintegrate or not, could this be a use of terminology — disintegrate to a layman (and I think that these are the people that are largely frightened/misunderstanding) means completely gone, maybe the comet has simply split into smaller pieces. Many Thanks

Of course no, comet not dangerous for us.
Аноним

It’s not dangerous, i.e. 2.4 millions km is safe distance.

Is there a brown dwarf or something else big behind the comet?

No, its just a comet, nothing behind the comet.

Hi, leonid. do you now anithing of gustavo muler and his pictures of comet elenin??? what happend with him???

Аноним

With Gustavo? I think all is fine, just comet not visible from North hemisphere since July.

Аноним

Thanks.
Agree, we not have another explanation of rapidly fading. Perhaps we will see something on Sep. 23…
Аноним

Because now comet not visible from the Earth. Since Sept 23 comet will passing through SOHO field of view. But perhaps comet will be very faint to see it.
Аноним

Hi, we will see soon.

Аноним

Spaceobs, please could you clarify that the above reply was about the state of the comet — not regarding the stock piling of food. thanks

The «triangular shape» is an imaging artifact.

«Astronut» (sic) is right on the spot! LOL!! Hoaglan (sic) is a pseudo! Don’t waste your time and/or money on him.

His name is Richard Hoagland — I would suggest that you pay him no attention, he claims that the triangle shape is obviously a tetrahedan shield. One must question how many of these he has seen in order to be so sure — I have him down as pure science fiction. I believe (though will stand corrected) that he was also behind the face on the moon nonsense

Hi, as I understand it regardless of whether it has broken up or not the trajectory stays the same, and remains as it always has been no threat to earth in either state. Perhaps some more qualified could confirm — thanks
