(meteorobs) RE:P/2006 T1 (Levy) orbit looks interesting!

[Esko Lyytinen]

Hi Roberto, Mikhail and others,

I think that the comet orbit is not yet accurate enough to derive 
conclusions many revolutions backwards and/or into future. And reliable 
trail-calculations are not yet possible. Maybe however 
trail-calculations from one and a few revolutions ago will show, if the 
trails behind (in time) the comet tend to come more close to the Earth 
orbit than the comet orbit or possibly the other way and may give some 
indication of timing relative to the comet node. And there is still time 
quite a lot to get a better comet orbit before the end of the year. I 
will probably not have time very soon to compute the trails, but Mikhail 
already seems to have a good start ;-)

Regards, Esko

Hello, Esko and all,

thanks for your message. I also noted this interesting comet. Elements
are still preliminary, but they give the following data set for
1901-2100 years:

Quite interesting that this rather big comet was on very favorable
orbit from 1927 and was undiscovered until nowadays and produced no meteor
activity. It makes to suspect that
its orbit is still not accurate enougth. But if not, it should suffer
a dramatic change after 2017 perihelion. Anyway, the comet deserves a
very close attention.
