Sorry for my bad English.

As I wrote in answering to Leo Stachowicz (17 January), I think that this
comet can to be periodic (with a period of dozens or hundreds years)
because it's inclination (1.85°) it's so little that there is only a
possibility on around 50 (90°/1.85°) that the comet come from the deep
space with a parabolic orbit, this naturally it's only IHMO, perharps this
it's not real. In general if a comet has a periodic orbit in 45 days we know
this, each day more this possibility it's littlest.

It's certainly for my bad English.

You are correct, but we must remember that the orbit elements shall change
newly and only in the next months we shall know the real orbit, I think that
we hope all that the orbital elements of the comet change in the right
way, following today data, in the second half of September (16-27
September) the comet should be of 3.8a magnitudine


and if the orbit of the comet it's really periodic it's possible that in the
old meteor data we can find outburst or a simple meteor shower
(with low ZHR), but this it's a work to do in the next months.
Best greetings.
