(meteorobs) Comet P/2006 T1 (LEVY)

Well, I made quick computations of trails from 1975 to 2006. It seems that
they do not show close direct encounters with the Earth nor in 2006
neither in 2012. My expectations
of activity this year have significanly lowered. But observations are
still very welcome, as there are lots of older trails, though
perturbed, but still very capable of bursts producing. This is even
more valid for 2012, as trails strongly perturbed by major planets
became "vertical" in coordinates "time" (x) - "rD-rE" (y). And in 2012 in
such coordinates system the comet will be just "above" the Earth being
at nodal crossing poing. So these "vertical" trails from the comet can
touch the Earth.

Best regards, Mikhail
