The Unification Epicenter of True Lightworkers

As I wrote earlier comet C/2010 X1 near its perihelion will be perfectly visible in the photographs of outer coronagraph SOHO . As I told Karl Bettems (Karl Battams, Naval Research Laboratory ), scheduled for special surveillance in the 4 different filters. Moreover, the estimated technical feasibility of temporary retargeting the spacecraft STEREO-B at the comet, the entrance of their close approach in late July - early August. Maximum convergence will happen July 31 at 13:00 UT. The distance between the objects will be only 7.4 million km (0.04956 AU).The spacecraft can pass through the dust and ion tails of comets. The second option is a bigger threat to the spacecraft. Let's hope that these observations occur and succeed, and the spacecraft without any problems will continue to further work on the sun-synchronous orbit .

Many blog readers have already seen the latest pictures of the cometC/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.

3 and 4 January at the observatory Faulkes Telescope North (FTN) observations were made the first Russian comet. With the help of two-meter telescope Folkesa, obtained detailed pictures of the coma and tail of a comet. The image on the left you can see a wide comet tail, long about 16 seconds of arc, as well as internal coma size 8h9 arc seconds.At the time of shooting the comet was at 545 million km from Earth (3.65 AU).

Posted my interview with news site "Gazeta.ru"
Institute of Applied Mathematics, Leonid Yelenin, the first in 20 years Russian, who discovered the comet, in an interview with "Gazety.Ru talked about how the discovery was made about its scientific significance and the equipment with which the comet was discovered.
Last night, Moscow time left circular of the Central Bureau of Astronomical Telegrams (CBAT).Awarded the designation of a new comet C/2010 X1 (ELENIN) . The orbit of the comet until preliminary and definitely will change, so let's talk about it later, but for now I want to say thank you to congratulate all of us and thank those who helped confirm the cometary nature of the object.

COMET C/2010 X1 (ELENIN)
Leonid Elenin (Lyubertsy, Russia) reports his discovery of a comet on
four 240-s unfiltered CCD exposures taken remotely with a 0.45-mf/2.8
astrograph at the ISON-NM observatory near Mayhill, NM, USA, on Dec. 10,435
UT (discovery observation tabulted below). After posting on the Minor
Planet Center's «NEOCP» webpage, other cometary astrometrists have noted the
object's cometary appearance. A. Sergeyev (Kharkov, Ukraine) and A. Novichonok
(Kondopoga, Russia) write that four stacked 300-s CCD images taken with a
1.5-mf / 8 reflector at the Majdanak Observatory in Uzbekistan on Dec. 11.0 show
a teardrop-shaped, very diffuse coma of diameter 6 "(total magnitude 19.1;
magnitude of nuclear condensation 20.7) and a tail of length 10 "-12" in pa
298 deg. WH Ryan obtained R-band CCD images with the Magdalena Ridge
Observatory's 2.4-mf/8.9 reflector on Dec. 12.47-12.49 that show the object
to be diffuse with a tail in pa about 315 deg. RS McMillan, JV Scotti,
and ML Terenzoni report that five 60-s R-band images taken through thin
clouds on Dec. 12.5 with the Steward Observatory 2.3-mf / 3 Bok telescope (+
90Prime CCD camera) at Kitt Peak in 2 "seeing show a coma diameter of about 7"
and a tail extending 10 "in pa 290 deg. H. Sato (Ota-ku, Tokyo, Japan)
obtained CCD images remotely with a 0.50-mf/6.8 reflector at the RAS
Observatory near Mayhill on Dec. 12.51 that show an 8 "coma and a 45" tail
toward pa 285 degrees.

The available astrometry, the following preliminary parabolic orbital elements
by GV Williams, and an ephemeris appear on MPEC 2010-X101. It is possible
that this comet is of short period.

On April 8, our next Observatory were carried out observations of Comet C/2010 X1 (Elenin) . Analysis of the results of observation indicates the rapid growth of the coma. In addition to internal, compact shell of gas is visible in the picture and produces over discharged outside the coma, its diameter is greater than 1 arc minute of arc, ie 80 000 km! It is possible that such rapid growth is associated with coma "overlay" on her dust tail of a comet, which, after the confrontation and remains invisible to the observer on earth.
Brilliance of a comet as abroad exceeded the 16 th magnitude and assessment Artem Novichonka was 15.4m. Such an assessment podverzhdaetsya first visual nablyudzheniyami comet obtained Jakub Koukalom (Jakub Koukal) and Juan Gonzalez (Juan José González), April 4 and 5, respectively. It is worth noting that another well-known visual observer of comets Hale, Alan (Alan Hale), who became in 1995 co-discoverer of Comet Hale-Bopp , was unable to discover a comet Elenina April 5 in a 41-cm reflector ...
From left sealed and one more event - the convergence of the comet and asteroid 4336 Elenina Jasniewicz . Here the proximity of objects that are shared by only 11 arc minutes, not an optical illusion, but a real, physical proximity of the two celestial bodies. At the time of shooting, the distance between the comet and the 6-kilometer asteroid was only 1.495 million km (0.01 AU) that exceeds the average distance from Earth to the Moon (LD) only 3.9 times. The maximum convergence of the two objects took place a few hours earlier, they are closer to 1.12 million km (0.008 AU).
