(meteorobs) P/2006 T1 (Levy) orbit looks inetresting!

[Mikhail Maslov]

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:
Minimal distance (MD) between the Earth and comet orbits:

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.

Best regards, Mikhail


EL> Hi,

EL> (I sent this once earlier today,. but probably it did not go trough. I 
EL> try again with some added text.)

EL> The new elliptic orbit of this comet looks interesting, as to possible 
EL> meteor shower. Have a look at:

EL> http://cfa-www.harvard.edu/mpec/K06/K06T47.html

EL> The orbit seems to pass the Earth orbit in less than 0.01 AU. This does 
EL> not mean that a shower or outburst should happen now but when the comet 
EL> orbit gets better derived, then some level meteoroids-trail modeling can 
EL> be made. The comet node encounter happens this year (according to a 
EL> quick lookup from IMO sol.long table) in the last day of the year at 
EL> about 21 UT. This is one hour before NewYear in our Finnish time! What a 
EL> good timing for a possible shower to "hide itself" ;-)
