Many blog readers have already seen the latest pictures of the comet C/2010 X1 . They tail of a comet's tail extends only 1 arc minute of arc. Is the comet's tail a little or is it just an optical illusion? For their calculations, I used a picture Gustavo Muller (Gustavo Muler) received by him on March 7. Unfortunately, the confrontation of the comet, we could not get her shots on the large telescopes - the camera is out of order seven foot telescope Folkesa (Faulkes Telescope North, FTN).
So, back to the existing snapshot. When approaching a confrontation, when the comet, the Earth and the Sun would be in line (ie, the angle C-C-W will be close to 180 °), the tail of a comet is almost hidden from the eyes of the terrestrial observer, because the tails of comets are directed away from the Sun. At the time of shooting, we saw the tail of the comet at an angle of only 2.75 °! Adopting the length of the projection of the tail for 1 arc minute of arc and solving triangles we see that the actual length of the tail of a comet has exceeded 900 000 km! Although in fact the tail should be even more so as Gustavo used only 30-cm telescope, it is clear that by removing at the same time a comet on a 2-m telescope, we would see the weaker parts of the tail of a comet.
If the March 7 we could see the comet's tail in the profile, its length in the picture would have exceeded 10 minutes of arc! Comet comes into confrontation and we have a good opportunity to get pictures of the coma of a comet. Maybe it will be done and on large telescopes.

Here are a few new photos ... Morris, you might want to have a look at these
Spaceobs has posted a new article about the possible connection between EQ's and Elenin ... they have been swamped! lol

Morris, I am not sure ... I have been watching GLP, and hunting down Gustavo and this other guy Bernhard ... they both have some excellent photos of Elenin!
I know Kim ... I posted my information, they can check it out on their own, or ignore it ... their play. I did my best
Amy, you are making headlines on GLP. Astronut(less) is down playing your comments there in a thread that is pinned right now (3 comets will be equidistant from earth in september).
