looks a little big

Of course, both the coma and tail are spectacular. Patient hope new images every day, because Elenin becomes more interesting. Thank you for every contribution Mr. Leonid.regards

Arkadi

Awesome, looks like a tail is starting to develop? If not, is there a educated guess when we would see it be more pronounced?

Does your comet still look to be on schedule for mid October viewing in the Northern Hemisphere America? Trying to buy a Telescope for this event and don’t want to miss it…I can actually see some heat now in the core.

Аноним

Yes, concert will be visible, you can buy small telescope or binocular.

Hello Leonid a question!

In the animation of your video is http://www.youtube.com/watch?v=LLIvMwxLZUQ enter from left to right, but real pictures of the comet is coming from right and left targets. Do the imaganes Stereoare reversed?.

I await your response.

Hello Edgar! Just another image orientation (flip).

Wonderful. My congratulation for these pictures.

Thank you Mr. Elenin for all the post’s on the comet and the video map above. I have a couple of questions one would be that The jpl browser I use seems to show The comet coming a little closer than your map does. Has there been many revisions in course of the comet since it entered the inner solar system?
My second question is have you been saving and do you pay attention to all the stories being written about Comet Elenin and yourself.? Does it even make you wonder about the comet, for instance the Coincidences involved in the Hollywood movie Deep Impact? As in two comets coming the big one now being Comet Elenin with a second comet actually impacting us Comet Hondo. interesting stuff it has to be amazing for you.
Either way thank you very much for posting on this blog , and if it helps when someone asks me about the comet I send them here.

A great Website to monitor Elenin whilst it is Visible in the Southern Hemisphere.. Enjoy

This is not real, comet is very close to the Sun, if we look on it from the Earth.

At now, comet on hyperbolic orbit (e>1), you are right. But on next decades, eccentricity will be decreasing because of perturbation by Jupiter. We can integrate osculating orbital elements for the future epochs. You can find this graph on my blog.

According to JPL Horizons:
Barycentric solution becomes closed (e<1) on 2011-Sep-01
Heliocentric solution becomes closed (e<1) on 2012-Apr-01

Thanks! I think what it may be smaller, perhaps 1.5-2 km. But if my comet will be observed by Arecibo radio telescope, we will know this parameter very well.

The data about C/2010 X1 downloaded directly from Minor Planet Center site to the Stellarium software, says:

[c2010x1_elenin]
parent=Sun
orbit_Inclination=1.8393
coord_func=comet_orbit
orbit_Eccentricity=1.000029
orbit_ArgOfPericenter=343.8056
absolute_magnitude=10
name=C/2010 X1 (Elenin)
slope_parameter=4
lighting=false
tex_map=nomap.png
color=1.0, 1.0, 1.0
orbit_AscendingNode=323.2271
albedo=0.04
radius=5
orbit_PericenterDistance=0.482458
type=comet
orbit_TimeAtPericenter=2455815.22299768

According this data, the comet has radius=5 (what means that its diameter is about 10 km). However, the data also says that its absolute magnitude is 10. Based in the table from http://neo.jpl.nasa.gov/glossary/h.html , the absolute magnitude=10 means that this comet has a nucleus about 25 km – 60 km. Do you can explain to us why this data seems mismatched?

MPC catalogs don’t provide information about physical size of objects. I think Stellarium use default value.
You can’t use this table for size calculation, it work for asteroids. m1 is “total” magnitude for comet, i.e. nucleus + coma. m2 is absolute magnitude of nucleus, but this value is very approximate. As I wrote many times, we can’t measure nucleus of comet if it is active. We need radio observations.

  If you can’t measure IT why do you think then it’s 1.5 km nucleus?

There is a far better way!

1. In Stellarium, go to Configuration (F2) >> Solar System Editor >> Solar System.
2. Click on “Import orbital elements in MPC format”.
3, Select “Comets” and “Download a list of objects from the Internet”.
4. From the dropdown list under “Or select from the list:”, select “MPC’s list of observable comets”.
5. Click “Get orbital elements”.
6. Check “C/2010 X1 (Elenin)” and click “Add objects”.
7. Close the dialog windows and press Control+F
8. Enter “C/2010 X1” into the search panel and press Enter.
9. Tadaa!

This way you can update comets and easily add others too. By the way, I believe you need at least Stellarium 0.11+

Please, stay tuned, I will post some news soon.

I was reading my news feeds and I saw a news about Astroid 2005 YU55. It’s written that in early November it will pass our earth pretty close. When I was checking its orbit from JPL, I wondered if Elenin and 2005 YU55 get close each other at any time. On October 12, 2011 Earth Distance of Elenin seems 0.242 AU and Earth Distance of 2005 YU55 seems 0.240 AU. So here is a question from a curious regular person who has no clue about space; (1) do we know or can we predict what will be distance between them? (2) would they attract each other? (3) If the answer is yes to (2) is it possible that one of them (specially 2005 YU55) may change its orbit? Thanks in advance for the answer.

Nice to se your discovery taking a trip on heaven :o)

On 16 October 2011, the comet will make its closest approach to the
Earth at a distance of 0.2338 AU (34,980,000 km; 21,730,000 mi)

why there is no better images of elenin?

Kevin Heider

Elenin is an average comet and is not at its brightest yet.

Comet does not decrease the size

Yes, this is C/2010 X1 (Elenin).
