The comet was discovered on December, 10 2010 by amateur Leonid Elenin, Lyubertsy, Russia. The first Russian comet, hearty congratulation!

If the comet will survive the Sun passage around its perihelion on 2011 Sept. 10.7282 in 0.48 AU distance from the Sun, C/2010 X1 (Elenin) could become a nice object for binoculars from mid October 2011 before dawn.


As feared, the comet dissolved during its nearest approach to the Sun in summer.

After some visual observations of  Juan José González Suárez and a ccd detection of Giovanni Sostero, Ernesto Guido, and Nick Howes, it was clear,
that the comet desintegrated  during its Perihelion. Both visual and ccd observers could confirm the remnant.

Similiar to images of collegues the remnant of comet Elenin is still visible. On this comet guided combination of 40 frames on the left,
the structure of the remaining dust and debris is rounded with a size of about 5 arcmin. (compare with
Jean-François Soulier's images)
The red cross marks the theoretical position of the false nucleus computed from MPC data.
A possible expected tail-like structure, affected by the Solar Wind, is not seen.


The ccd-show is starting slowly ....

Since one month the low magnitude level is very constant. This comet must have good luck to survive its perihelion.
